tpr60 · 03-03-2012

90 zr 63000 miles, changed plugs, wires, one coil, changed 6 injectors[rest ohm OK], fixed vacuum leaks, updated GM prom. Has high hydrocarbons at idle, over 300[needs to be under100] 2500rpm reads 120HC, o2 at tailpipe is 5[should be zero]. My understanding is the car is running lean. Any ideas, comments, or do I need to register it out of state[Calif].
