I have a 94 z29 Camero with a 350 LT1 motor i have done some work on it replace parts headers and plug and wires I put it back together it ran fine took it out for a ride it ran good for about 20 mnts and all of a sudden it stalled out I started it and now it sounds like it's running on half power anybody have any ideas I would appreciate it

 

Could be a lot of things,Optispark? Fuel pump? Injectors plugged? Battery or Alternator? You need to get a code reader on it.

 

Ok thanks I'll try that and see what If I can get a read on it

 

My 3.4L V6 GM engine is more powerful today than it was back in 04. I changed out to Mobil 1 soon as I got it home. Been using it ever since. Changed out OE air filter to K&N. Changed out restrictive exhaust to dual exhaust with 1/2" larger pipes. Changed out to new OE plug wires.
