2009 Aveo Bucking/Jerking/Losing Power

[moods5588]

I have a 2009 Chevy aveo5 LS. My car runs fine but then will randomly lose power and by power I mean that no matter how far a push down on the gas pedal it wont accelerate. When this happens it's like turtle speed trying to pull into a parking lot or anywhere to get off the road. I noticed this last time that if I shut my car off and then wait a couple minutes it will drive fine but the check engine light stays on for a little bit and then turns off. Every time I have tried to get it scanned at any auto parts store it shuts there scanner down and are unable to check anything. Anyone know what would be the problem? I have read a lot of people saying catalytic converter but I'm not sure if thats my problem. ANy help would be greatly appreciated

I've got the same problem with an '09 Sedan LT, though I can get codes off my OBD2 reader, have you tried to do anything to fix it? So far I've replaced the spark plugs, cleaned the throttle body, tried swapping the fuel pump relay and run cleaner through the fuel system. I have a replacement coil pack I'm going to throw in as soon as it gets warm enough to see if that does the trick.

I had that happen in my '06 just a couple of years after buying it. It turned out there was a cracked vacuum tube connector. The crack was so small I couldn't see it at first. Had a helluva time finding it, but after replacing it, no more problems for a long long time...

Can you give me a general idea where that vac line was located?
Thanks in advance
