ok got codes, what does it mean?

[Layz]

i got three:
0068 said it was manifold pressure, throtle position correlation.
0339 crankshaft intermit
0633 Skim key not programed in PCM

This all happened with a few days, any ideas? I have looked at wires and they look good to me.

0633 skim key, means you have stage 1, 2, or 3 and need to get it flashed with the skim key at your dealership

[scarface2jz]

you also have a boost leak, or you overboosting... and the crank position sensor is common, need a new sensor

[Layz]

The sim key can just go? glad i kept my original PCM. Guess i'm headed to the dealer this weekend :)

[sarty4]

curious, when was the last time you changed your plugs? and whats the gap?

[Layz]

Last year, also did the wires with the MSD ones, think they are 8.5. The gap i believe was .23.

.23 is too tight...open them up to .35

The only thing chanig the plugs did was make them look pretty. Still have major stumble when i go about 13% or so on the gas.

Stock coil pack?

[Layz]

Yes, i was thinking about that as well. It's just wierd, it is ok just seems like it goes fine i get into a certain band then it has issues. Once i get out it is fine

[oo3menace]

Have you boost leak tested the car? Possible injector leak/manifold gasket? What other mods do you have? Stock fuel setup? Do you have a wideband? Do you hear a whining from the fuel pump/tank area? Are you using anything to tune with?

Last of the PSI-FI cars, It is their entire setup. Turbo 50 trim, manifold, power-paq, and traction bars. No boost leak was done on the car as of yet. I was thinking about taking out my stage 1 pcm and putting back my original, just to see if it is the pcm. I still have to check the TPS wires, so hopefully i can do that tonight.

[sarty4]

Yeah .028 is tiiight IMO

malfunctioning ppq? Do you know how to tune/use the ppq software? Does your ppq have the vac line attached to it? Is it ripped/damaged? What type of fuel upgrade did the psi-fi kit include?

im 100% sure if you change both your problem will be solved

Sort of, i took a look at the map that is in there. Just a bunch of numbers to me to be honest. Not sure if - means more fuel or not. Looked at them and it has - increasing as RPM gets higher. I would think that is wrong but the car did work fine before. I'll replace the sensors can't hurt.

[Layz]

Ok i give where is this crank sensor? and if i was to test the TPS what are the volt readings i'm looking for?
