Re: Power surge at off idle
What kind/weight oil are you using and is the level full? Do you have a way to check the oil pressure? That's the first thing I'd check AFTER I cleared the code to see if it comes back within a day or two. If it does, I'd change the oil pressure sensor. I am not so sure that this problem is related to your surging though. I once got this code, cleared it, and it never came back. I still have a new sensor sitting on the shelf just in case though.
It could be a TPS problem, but I think I'd check the transmission fluid level and condition first. When is the last time it was serviced? Does it up/down shift properly? Any hesitation when going into gear, especially the first time after its sat for a while? Does it slam or "ooze" into gear when shifting from reverse to drive or drive to reverse?
Bottom line, eliminate the easy, inexpensive stuff first, and then go from there.
