i own a 97 camaro rs with the 3800 series engine... i did a tune-up on it (new plugs, wires, etc.) and when i pulled it outta the garage it was coughing and popping like chitty chitty bang bang. My bill is up to 400.00 so far and it's not any different than when i brought it in. On diagnostics it's fine but driving it is horrible. Going up hills or whenever else the engine has to work a lil bit it shimmies and sputters and has no power whatsoever. I need help, i'm running outta ideas and money!!!
