An update .
Because my Camaro dealer doesn't know it anymore and GM can't tell them what's wrong with my Camaro, i have been experimenting by myself.
The results:
- The problem occurs in tour and sport and in manual and automatic.
- driving away "fast" instead of slow, largely solves the problem but it is not very neat to drive away "fast" in a residential area in the morning.
- driving away in manual, in second gear, also largely solves the problem.
- starting the engine and hitting the pedal till about 4000 rpm once or twice makes the problem less but it is not away totaly. But that is also not very neat to do in a residential area.
I would like to add an MP3 file but i think it is not possible to upload a "sound file".
I hope someone has an idea because it's driving me crazy.
Is there maybe a person active from GM at one of these forums who can also look at my problem?
Are there any sensors in the car which adjust the fuel mixture, making it possibly too rich (or maybe to lean)? The "peng peng" sound i hear looks like fuel igniting in the exhaust.
Thank you in advance.
