Finally got mt profec B issue cleared and tuned the car for 10psi. In third @ WOT it felt like the car broke up a bit. It DID NOT feel or sound like detonation. I ran it in third and fourth to tune. Once tuned it seemed to do it around 4000 rpm but picked back up until redline. It did it twice in about 5 runs. Also went WOT in first and second...it felt fine.. I don't want to run it again to be safe.Any ideas? P.S. I do have a new fuel filter so not that.

 

Running 93 octane. Probably will go get some higher octane and try again...

 

Broke up meaning? Bucking, backing, ect. It might be transition or the 3.5k hickup.. Do you have new plugs was it working fine before install of the profec?

 

Maybe you need new plugs and wires ?

 

Sounds like ignition breakup. You should replace the plugs as mentioned, upgrade your engine grounds. You can also add some to try and cut down on the break up. You also could try an aftermarket ignition module.

 

Either plugs or that would be the best bet. HKS simple from what Ive heard maybe 15 minutes? with the adapter.

 

Do the plugs...

HKS is simple and I recommend it but it is a bit pricey and most likely just switching the plugs will fix your problem.

Thanks guys.. I thought about it being the plugs. Will change on Monday....

 

15 minutes? Try like 5 minutes with a 4 minute smoke break

 

Maybe I'ii try that also.

 

I have new MSD ignition wires. It should have been in my sig. Will add. Sorry. Duh!
