Cam Pos sensor put my car at the dealership for 45 days while it was in warranty awhile ago. Part was on national backorder. They picked up my rental car [Cavalier ! ] for the whole time. No miles put on mine.
Car did throw a CEL showing this fault after the 3rd time it hiccuped at 3500 rpm in second, third or fourth at WOT.
Car was still drivable but had that slight interuption in power delivery. I could make it do it any time.
Replaced, fixed, no prob since. ZZZ.
