My aveo was being a little lumpy at idle so I decided to use some seafoam. Well I sent it in through the PCV like it said but instead of only putting in 1/3 of a bottle the aveo quickly sucked up almost the whole bottle! Now I'm throwing a CEL code AND a HOLD code... and the car is running even more rough! So just be careful people! I hope that if I let the car idle for about 10 minutes maybe it'll clear up....
seafoam? isn't that the crap that accumulates by the beach?
ha...ha... no...
it's a cleaner you can buy at any auto parts store
so yeah my engine light is blinking, along with the hold light. I want to take the car to Autozone to get it checked with their machine, and since the people at Autozone aren't always the brightest where is the port that they'll hook the scanning machine up to so I can tell them?
its under the dash driver side, someone correct me if Im wrong...but I believe they are always there
On most "domestic" cars (including the aveo), yes... but on my OBD2 VW it's under a trim panel by the ashtray/cigarette lighter... so not always there.Quote:

usually blinking is a misfire, pull your plugs.
yeah i plan on checking those, depending on what Autozone says. I hope the seafoam didnt foul them up because they are e3 plugs and about 15,000 miles old at most
good news and bad news. went to autozone and the scanner had 2 codes, both misfires. Pulled my plugs and they were icky brown! So dropped some new plugs in and now the car runs awesome, but my engine light is now on consistently not blinking, i tried the trick where you unhook the battery and hold the brake pedal for 30 seconds, and to start and turn off the car 3 times, but the light remains. I decided to leave the battery unhooked now overnight and see if that helps. If not i guess i'll have to go back to autozone in a few days
I'm thinking you fried an o2 sensor. You might be able to pull them and clean them up with a brush.
i might have, i'll have to see what happens in a few days
just go back to autozone and have them clear the codes
this morning, after leaving the battery unhooked over night, the engine light went away so all is well.
What rpm does the auto shift at? I swear it used to shift at 5700-5800 and now it looks around 6200
mine shifts at about 6200 but i dont like to run it that high
Seafoam is great stuff. It boosts octane, use it in my bike when I can't get #1. Cleans your fuel system really fast and well and is better than fuel stabilizer. I used to have fuel trouble on my bike at the start of each riding season but with Seafoam it is not bad. You still want to get fresh gas in ASAP but it keeps everything clean.
BUT too much is no good. Putting it in your fuel is no problem but as an additive to any oil you have to be careful.
