got a 92 z28 with 5.7,bought off my brother.stumbles and skips when hot.car has had a new fuel pump and filter distributer rebuilt ...module,pickup coil and shaft..etc gonna ohm out injectors next, and also this car has a autozone ecm in it that my bro put in,seems to have gotton worse since this,just curious if anyone has had a similar issue.car has also had new plugs wires and cap. car has 130000 miles.thanks...jeff

 

I had a similar problem with my car and it was the injectors. When the engine is up to temperature and operating in closed loop the problem really becomes obvious. I would ohm the injectors when they are cold, and again when they are hot. I had one that would ohm ok when cold but was terrible at operating temp.

 

thanks for response! yea im gonna ck them hopefully tonight,time permitting!! do you have any suggestions on what injectors to get? or any good sites.this is a everyday driver.so im kinda looking at something not to pricey,thanks
