Hello folks,

It has been a while since I posted here about's, but I am having issues with my girl and thought I would see if the experts can help me out. I have a '07 GT with bolt-ons (see my sig) and everything has been hunky dory for the last couple of months...until yesterday. Started her up and started home from work when after about 100 yards she started missing on at least 2 cylinders and sputtering like all hell.

TS:

Immediately killed the engine and parked her.
Checked for error codes (none).
Checked Vacuum Connections and COP connections (all tight)
Restarted (same problem)
Reloaded Tune (same Brenspeed tune I have used for over 2 years), same problem.
Disco'd Battery, reloaded tune, same problem.

I parked her last night and will tear into the FI/Plugs tomorrow on a buddies recommendation, but wanted to check as all of the Error Code descriptions I am seeing indication a Cam/Crack timing issue. I am worried that I jumped a tooth on the TC, but I didn't think that was possible with these.

Help me out guru's, any ideas?

 

Ok, have you looked the codes up yet? Did it go into "fail safe" mode? Sounds like what happened to me when my TB voltage wasn't correct on the BBK

 

No Failsafe mode (no wrench).
TPS Voltage was checked and calibrated during installation. And has been trouble free since day one (FWIW)

P0021 "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)
P0018 No Information Found

 

Mine worked great from day one, a few months later it just went crazy. Not saying it's that but start with the simple things. It threw so many codes it wasn't even funny.

 

Don't think that it is the throttle body in this case (I just rechecked the TPS Voltage and it looks good), though god knows they can wreak havoc. Any other suggestions?

 

Update for those whom are concerned, or even have the same issue. Turns out that the VCT Solenoid broke in two during a cold start and locked the Cam (by clogging the oil pathways). This of course caused the Cam to stick in a artificially retarded condition (and eventually throw the error codes). Turns out to be an easy fix, a couple hours of labor at the tuner, and $118.50 for the glorified butterfly valve.

Drive safe folks!

 

Didn't see this until now, but P0018 is " Crankshaft Position - Camshaft Position Correlation ".

Norm - Havn't seen you chime in recently, good to hear from you. Thanks for the update, that error code was driving me nuts (though my mech. had it figured out in a couple of minutes LOL. In any case...just gave me an excuse to get cammed =)
