What is the fuel injectors resistance supposed to be my injectors 1.2-0.9 some were 1.5 would this becausing the missfire after warmup2-3 min after starting i was the one had bad head gasket fixed that not leakin the leak down came negetive.I need the ohms resistance on them please.

 

So Itwasn't the fuel injectors what about the ecu dont they control the the spark and fuel can this cause the missfire. how do you know when they go out on my pontiac thats how it will run when it missfired.is there way you can test them?Cause it can be in backup mode.

 

Ecu is ok I found some freid wires one right under the distributor cap that is black, plugs in by the theromostat or under neith the distributor looks like a ground,another to the eacv behind the intake,another for distributor ignition wire going to try to rewire those and see what happends.

 

Hey how do you tell if the valves are bent because my compression is very low 90 100 90 120 can this becausing the missfire?

 

fixed it ok now.
