A bit of background first, 2.5 hybrid, VF-39, STI cams, deatschwerks 565cc’s, and a tune
The issue: about a week or two ago the car started to idle rough, shortly after I got a CEL, p0171, and then it got worse and P0300, P0302, and P0303 joined the party. If I clear them, it will come back on after letting it hot idle for 1-2 mins, and would never come on if I could keep revs above 1500 at all times while driving it. While it is idling it does have a pretty good shake to it and has stalled on occasion, runs smooth in upper rpm ranges. To this point the hybrid has 5k mi on it, and ran perfect up until the CEL’s. To the best of my knowledge I am most likely having issues due to A- MAF sensor, or B – front 02 sensor. There is also a possibility that I skipped a tooth on the timing belt-doubtful.
Any additional input would be helpful, but the real reason for the post is to locate a generous enough person to let me borrow an 02 sensor/MAF sensor to try to determine which $250 part I need to buy.
Thanks
BRAD
