Hey everyone, I don't know if I post this from my phone if it will show my sig. Here are the details. 99 Trans am bolt on 228 cam tuned 157k miles. Most times when I get in to drive it when the engine is cold it will miss/stumble when I'm trying to accelerate through a intersection etc. once it is warm it does not do this. Any ideas?

I recently had the same problem and realized some of my spark plugs were loose... may be the same for you.

I will def check that but it wouldn't explain why it only does it when my car is cold

Try cleaning the mass air sensor.

i just found out over half of all my plugs were loose and backed out. enough to be removed by fingure tips. that was quite disconcerning to say the least.

Mine runs rough for a few after I pull out of the driveway in the morning, but quits in about 1/2 a mile. Didn't start until the car was cammed.
