Just a quick question. My Car bucks in 1st gear at idle speed. No gas from the pedal. It is just like a large Cam buck, but to a lesser extent. I bought the car used and all that was done to the car was the headers and TSP true duals, which seemed true before I asked what was done, as it was the only thing i noticed as well. I think the cam is stock, as I hope it is, as everything else looks stock, and that there is no lope to the idle. But who knows.

In other words, is mild engine bucking in a 99 model year M6 in 1st at idle speed normal?

Yes this is normal. It's called surging. My stock 2004 350Zm6 would do it when at low idle speeds in 1st gear. If it had a cam it would surge on cold startups while not in gear..

mine does it a lil too, i usually give a pinch of gas to keep it from that.

the pcv valve has a rubber hose on it and sometimes it crackes and starts sucking air from it. It wont set a check engine light but it will make it buck especially at idle at a stoplight. check it out. a piece of heater hose is a simple fix
