Will start and run when cold, idles fine, warms up and starts to pop at idle and run rough. If you shut it off it won't start again for 2-3 hours if it does start it runs like above. Rough. No codes thrown. Injectors are not pulsing correctly on a scanner. I put in a new distributor, didn't fix it, checked the computer. Didn't fix it. What else can cause this? It's a 92 tpi 350 z28. Now going through wiring to distributor and on the car to see if it's a wiring or ground issue. I need it fixed fast.. Any ideas?

 

Can you check your sensors with the scanner. You should look at your cts to be sure it's not flaky when gets hot. You might be onto something with grounds though, check all those too.

 

Sensors seem fine.. Still lots to check.. Looking for more ideas..

 

It's the injectors apparently... They aren't ohms correctly.. 5 out of 8 were below 16. 3-4 were 5.. One was 1.
