Ok im getting a misfire cel 74. My car drive and feels normal. I have no idea what is causing this cel. I have changed distributor cap and switched to another working dirstirbutor. I have changed new spark plugs and new spark plug wires.
I swapped around the injectors and still i get this CEL!!! When im using the obd1 ecu, i get no cel. Its only when i run the obd2 ecu.

Compression checked out good.

This all happened when i went back to stock from being boosted.

I want to install my setup again and get it tuned, but i would love to find out whats tripping the obd2 ecu.

Help me get boosted again

 

 

TTTTT

For reals. Ive seen threads on here with people having the same problem. But the sad part is, it seems like no one ever gets a solution...

I wonder if its just a sensor?

 

from what iv been reading ..... things that might cause this ....

bad coil / ignitor
valve lash adjustment
in some werid cases the IAC was replaced and solved problems


i unpluged my iac and it seems to be working good ..
have no tested my coil yet
and my valves i think need adjustment

not sure if it would cause this .. but just from searching countless threads

i ll be testing my coil sometime this week

and hopefully get my valves adjusted before the week is over!

iv still got misfires
