Needing some assistance with what I feel to be an ignition issue.

[Blakonblak94]

Ok new coil, new rotor, new tfi, new pickup, still cutting out. I'm gonna put my factory fuel pressure regulator on and see if it's messed up. This sucks.

 

[mikey94gt]

check grounds.......?

 

[Blakonblak94]

Will do. Here is a question on grounds. If I have two different grounds on one screw will that cause any issues? I had an ex-service tech go for a ride along today and he said it wasnt like anything he's ever dealt with before. Ill be able to video tomorrow.

 

[mikey94gt]

No, dont worrry about that. you do need to ground your engine to the negative terminal on the battery, along with the engine wiring harness and ECM

 

[Blakonblak94]

Are you saying add those grounds? All factory grounds are still intact.

There's another member (slo1) who had a miss like you, and like you he replaced all of the ignition parts with no help.
The last thing he did was a compression test and found 1 cylinder to be waaay low, Pulled the intake and found 1 of the valves not opening all the way, chased that to a dead lifter.

Then your good. I would do a compression test, that sounds reasonable.

I just pulled all my plugs, they look pretty bad, and when plugging one of the plugs into the coil wire the spark was orange and not consistent. Shouldnt the spark be blue?

 

[mikey94gt]

Ya, it should. what plugs U runnin?

I was running autolite 3942's but i bout some motorcrafts a few minutes ago to try. Still the same issue. Im hping the video works.

 

[Blakonblak94]

I know the video works but I do apologize if it actually takes yall to my page. My photobucket is acting an a*s. Correction it should work just fine. Here is one other thing I noted today. If I unplug my maf it still funs the same as it does with it plugged in. Like identical, the idle and all. I wonder if it could be a culprit? I may swap back in my 19's and maf tomorrow just to eliminate that from being a possibility.

Did you ever happen to run a cylinder-balance test (after pulling codes)? If so, it should have let you know about any cylinder(s) not contributing properly.

 

[Blakonblak94]

It gave me a code 9

 

[Blakonblak94]

From my reading I feel it to be a bad Maf. Seeing as how I unplug it and nothing changes and the missing only occurs at wot which would mean it is dependent upon airflow through the Maf. I'm gonna give it a shot after work. If it is what should I do? It's a 2 month old pro m.

 

[mikey94gt]

I would say so.

 

[Blakonblak94]

Ok, so Im not even sure anymore. Swapped in my old maf, with my 19's and the car did the same thing. Wondering if my computer is done now. Im just so lost. This has sucked and I cannot for the life of me understand why its doing this.
