Okay, let me start it from the beginning and take it on through. It all started after SHOCAGOs drag day. After leaving the track (32 runs later) i noticed a funny sound from the driver side under the hood.The car drove fine and accelerated fine for the most part (didn't have a LPM installed w/ a Cobra 80mm MAF) so i wasn't worried.

So then the caravan stopped at a gas station to fill up and the problems began. The car idled extremely rough and the trans became a riot to shift, that is if you could get in gear at all. (MTX) So i drove it home and then noticed that 1-2 shifts were the worst. Even downshifting into 2 wasn't hard. Keep in mind that all gears were a pain in the **** to shift into about 5min before only the 1-2 shift became a pain. The car continued to run rough.

So i scan the codes and behold the results.
Code 15 - ECA Memory Failure
Code 25 - Knock sensor was not sending a signal

Now, what the **** is the ECA Memory failure about? I plugged in the LPM and the car ran considerably better while driving at higher RPMs. It idles extremely rough and burps quite a bit at 1,500-2,000 in all gears except 1st.

I did happen to have the LPM plugged in while i scanned the codes. I was advised that the LPM could cause such a trip? So then would the knock cause the idle problems?

Running an 80mm MAF without an LPM will cause your car to run lean. THe only MAF that won't cause this is the Pro-M. Taking all those runs at the track might have caused some major wear on your tranny's syncros and blocking rings. :( It might be time to invest in an LSD and trans rebuild. Especially if you plan on taking that many runs at the track. eek!

I've figured this much out. Too bad nearly all the syncros are obsolete according to SHOnut!

As far as the 80mm MAF, I am running a LPM now and the power difference is just.. FREE POWER! (LPM came w/ the car)

Now i still can't figure out why the car is running like dog crap. Is that normal for the knock sensor to stop working out of the blue?! squint
