Agghh. The CEL did come back on and I will be checking that at lunch time and will update that info. I have no idea what's goin on.


Is it possible my headgasket is seeping? Although I am not missing fluid.



I put some new fuel in it with some injector cleaner so time will tell of that helps at all.
Per my post above, have you checked for boost/vacuum leaks yet via pressurizing the intake yet?
One potential issue is a split vaccum (or charge air) hose that weakens with heat. A boost leak check will detect this (and an ordinary smoke test won't).

Here's another thought (while we're on the topic of split hoses):

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
