If I unplug my maf, nothing changes to the cars runabilty? Checked the pigtail and it is getting 12v also.

 

OK, Im getting out of options here with my car. I really don't have this much experience with dealing with a phantom misfire that I have no idea where to start looking. The MAF doesnt seem to be the issue since i replaced it and there is no change, i have replaced the plugs and inspected the wires thoroughly. Does anyone know where in the Portland are i might be able to take it to get looked at? someone who knows the LT1's?

 

what are the spark plugs gapped at ?

 

I don't know? Whatever they came out of the box at? They are the NGK TR55's I was told they are an upgrade for my car. Should they be different then what comes from the box?

 

You mentioned that the plugs on one side smelled like gas. Have you checked for any injectors that may be leaking?

 

Do I just pop em out and turn the key to the on position? or is there a procedure?

 

That is one way to do it by removing the fuel rails with the injectors still attached and turn the key on and see if there is leakage. You could also put a fuel pressure gage on and turn the key on and see if the pressure leaks down quickly.

 

I will try by removing the injectors out tomorrow, the car misfires so bad it can't be driven, Idles ok but anything over 1500 rpm just goes horrible.
