How cold was it this morning? Also, did the Check Engine Light come on?

One thing to keep in mind is that the camshafts are "controlled" by oil pressure and as I understand it the orifices feeding the hydraulic actuators are not very large. If the oil was especially viscous due to cold weather, the camshafts will not advance properly. The PCM detects this, will set a code or codes, and then go into sort of a limp mode.

That's the best I can come up with at this moment. I'll check Oasis when I have a moment and see what that says. Please provide the DTC numbers, if you remember them...

-20 celcius today...not especially cold....driven it at -45 celcius with no probs.....no CEL either. yeh, limp mode is what it felt like. hills were a :censored3: to climb, i put it in 3rd to try and bring the revs up, to no avail. it seems to be working fine now...altho i haven't driven it yet. the test will come on the way home thurs afternoon. if it happens again, i'll grab those codes. it reved fine when put back to stock, and is still revving fine when i installed the 87 perf again...i didn't touch any other options...basically no custom program. thanx Bill.

Cold weather and cams working with oil psi are no fun.....Update us if it happens again. What oil are you running?
