I have 2002 trans am with ls6 patriot heads and 283/283 230/230 @.50 dur 114.0 lobe 572 572 valve lift and I had it dyno tuned but it stalls all the time and has a cam surge like problem when cold it also smells very rich any ideas?

 

Sounds like you need to get back with your tuner... when did it start doing this? or has it done this since you've got it tuned? Did you chance anything? Is your check engine light one? need more info here

 

It started about a week after tune engine light goes on and off. I thought it was from o2 sims. no other changes

 

Some how you might have lost the tune, i would take the car back up to your tuner and see what he says.... what codes are you throwing?
