i have a 06 and 2010 aveo ..i just replaced engine in 2006
and im getting a misfire code too ,,,and a po317 code(rough ride something )
i just spent 550 on low mileage engine
115 on clutch 360 in labor and a huge tow bill to get me back to wv ..
im outta extra cash
is there anyway besides dealer relearn to fix this
and if i just drive it ,,what happens
Well i know its been a bit my mom didnt have the money to repair the car right away. The car is a 05 and i got a 06 motor complete for $450 i swapped all the crank cam and knock sensors from the 05 to the 06 and the 05 manifolds and new timing belt while i was there. It started it right away it threw a p0300 code with a flashing hold light. I tried a crank relearn with a snap on modis and i tried a otc scanner neither gave me te bi-directional option to do it. I took the car to a local shop that had a tech2 and the did the procedure. It fixed the misfire p0300 code and it passed CA smog test. So i can confirm this swap worked for me.
I am not getting codes but I am having problems after installing the rebuilt head on my 2004 Aveo with a previously installed and working 2005 Pontiac Wave engine (it had 90,000 km and 80,000 in this car when the tensioner blew up). My problem is uncontrolled rpms on start up. I can get 7500 rpms and still rising immediately on start up. I have looked at various relearn procedures but I have tried the TPS relearn procedure a couple of times and that had no effect. I have even swapped in another ecu and got the same result. The only positive I can take from the whole exercise is that this little engine can really rev much higher than I would ever have expected. The local dealer does not want to touch this engine and is the one who gave me the TPS sheet with the instruction, if this does not worked please have it towed somewhere else. If you call and ask for me I won't be here... So I am trying to understand what another dealer needs to do before I have it towed 25 miles to have them turn it away. Rocky
so it starts and revs immediately to 7500 rpm? does it come back down?Quote:

I then disconnected the cable throttle and the engine plateaued at 4500 rpms after wild acceleration on start up. I then tried disconnecting the TPS, and IAC sensors and got the same results max revs of 4500 with cable disconnected.
I switched to 2 other throttle bodies and got the same results, wild acceleration to way over 6000 rpms before I shut it down. Thottle not connected 4500 rpms after wild acceleration.
final test was swapping out the computer with one from another aveo, base car with stick and no air. Same results, wild accel to more than 6000, Finally after an intense amount of reading I found the aveo has a rev limiter so I ran a couple of tests and let it go on start up. The revs went wild and somewhere around 7000 it cuts out and then when it drops, it roars go back up and then cuts out again. Not a really efficient governor but that is how it works. I went to the Chev dealer and dropped it off with instructions on having the RELEARN procedure carried out. I tried it but could not get it to take. Rocky

i will be interested in the results.
I can't believe the car gets stupid so easily because the battery has been disconnected for a period of time. Given the number of aveo members carrying out timing belt changes and head rebuilds I am surprised more of them are not voicing the same complaint that I an. We obviously need a list of the procedures to be followed to get these engines running properly and our cars back on the road. In my local parts yards the number of aveos with battle damage is 1/3 to 1/4 of those with damaged heads due to belt /idler failures. Rocky
i don't disconnect the battery when i work on anything unless i am doing fusebox/ecu work.
likely hood of crossing pins and damaging something when the key is off, is slim..
Call from the GM dealership today? They are puzzled they say the engine is running with the throttle closed, YUP I told them that, and that it runs without any throttle body at all. They wonder where it is getting its air with the throttle closed. So is there a real difference in the aveo heads beyond the different intake manifolds?? Mine is simply supposedly from a 2005 wave and a 2005 aveo. I know the head is new to the engine, but the intake manifold was on the engine before the idler failed and tore up all 16 valves. ANY SUGGESTIONS OUT THERE IN AVEO LAND?? THANKS Rocky
for that much air, it has to be coming from the vacuum booster on the brakes. Unless the pcv or egr were not hooked up.

1. They say the engine computer is not communicating with the car|?? but the check engine light is on.
2. There is now a large oil leak on the bottom of the engine on the passenger side, but they can't seem to understand why. The leak seems to be "ON related", when off it is not leaking.
3 The engine is making a strange cyclical sound...
I suspect that if the timing belt cover is removed, they will find the answer to the oil leak. Although it wasn't your fault, this engine was essentially red-lined repeatedly before even having enough time to distribute oil properly. This is probably not a real happy engine right now. With more $$$ it might be able to come off life-support, but what's the long-term outlook going to be? JMHO, but if it were mine, I would pay the bill and bail on this one (unless it's worth it to you to drop in yet another engine).
\So what do you think has happened? If I pull the oil pan gasket am I going to find the answer? Never had an engine that far apart? I don't really fancy having the gm dealer tear it apart at $150.00 an hour to tell me it is toast. Although I am starting to get the feeling this will be the diagnosis, unless it is something obvious like I cracked the oil pan with a jack. Thus my question about the damaged engine on the aveo list with a massive oil leak in the passenger side end that was posted back in January 2012.
I have another Aveo block in my garage I bought to use as a training aid. The block comes complete with pistons etc that move up and down. It came with a damaged head... Theoretically I could build it up with all of the bits and pieces from this engine that self destructed and then install it in the White Zombie. Rocky
My guess would be a partially or fully blown (not that it matters which) crank or cam seal. But what really bothers me about this is all of those 7K RPMs. I'm trying to imagine the effect of getting in my Aveo, turning the key, and immediately flooring it right up to 7K without any warm-up whatsoever. Once MIGHT not cause a problem, but doing it however many times yours did just isn't a happy thought. But, I'm no automotive engineer, and maybe one of these engines could take punishment like that. Bottom line - I wouldn't ever feel comfortable with this engine, even if someone could get it running again.
This is a further post to identify some of the answers to the problems I posted earlier today.
Problem #1 no resolution as of yet.
Problem #2 The oil leak is presumed to be the result of a leaking intake camshaft gasket. The GM dealers wants 5.7 hours to change the cam gasket.
Problem #3 the strange cyclical sound is a result of the dealer tech installing the harmonic balancer incorrectly when rechecking the timing cock-eyed you got to put the balancer hole in the keyway before tightening it down.
This engine now runs smoothly while leaking oil faster than the Exxon Valdez or an Enbridge pipeline! Will post if a new intake gasket solves the oil leak. It only leaks oil while running.
It is Halloween and the white zombie gets another chance at life. Rocky
I just bought a mint condition 2005 Aveo LT last night with milky oil.. The previous owner already replaced the head gasket, but the cylinders are still getting water pumped in, and the coolant surge tank has bubbles.. I am thinking it probably has a cracked block..
Two questions:
1. Am I missing something? (I am a competent mechanic, but very new to the Aveo)
2. Can I swap in an engine from a 2009 Aveo?
Based on this thread it seems like the general consensus is the only difference is the fuel rail, injectors and sensors between the 2005-2009 model years..
I see a few people saying the CASE (crankshaft variation relearn) resolved any differences between the engines..
All of this assuming I work out any "real" CEL errors that pop up such as O2 sensors or disconnected wiring etc.
Thanks!
the 09 is the start of a whole new engine. it can be put in, but it is a swap, not an exchange.
the head could be warped, but with the aveo it is very very easy that if you do not follow the torque pattern, that the head gasket leaks. you also have torque to yield bolts.
i don't want to say you can't trust another mechanic, but even if the previous mechanic didn't clean the old gasket enough before the exchange, would cause a leak.
So I should be looking for a 2008?
This car has 150k, and had been run xxx miles with antifreeze in the oil, so I am thinking of finding a new engine with lower miles, changing timing belt, water pump etc. and dropping that in.
I will probably pull the head on this one to take a look before I pull the entire, but I don't see good things coming if I try to fix it.
Well I went to NAPA and they actually had a new camshaft oil seal in stock. Replaced it and the problem with leaking oil is gone. It is 3 months later I have another 3,000 km on it and the white zombie trucks on through the arctic snows here in Northern Canada. Go SNOW ZOMIBIE!!!Quote:
