+1 vote
My 2002 chevy S10ls 4 door 4x4 4.3l started out with a intake manifold leak, mechanic changed Gasket. After this I got a p0302 code so he replaced spark plugs, wires dist. cap rotor code still there. he replaces complete disturber now code crankshaft sensor and misfire still there.he replaces crankshaft sensor back to cyl 2 Misfire. next injector was replaced still cyl 2 misfire and now evap.system leak. He checked compression electrical spark plug. He is telling me now that it needs to go to a dealership to have their analyzer marry the new sensors with my trucks computer. Anybody have an answer he has had my truck for 5 weeks. Now he has replaced knock sensor. I went and got the truck out of frustration and found the Tach Wire from the remote starter cut i am looking for others. I can't figure out why the oil pressure gauge shows low oil pressure at idle once the misfire starts. Anybody seen this before?

A visual assessment indicated that new start attachments, sparkle attachment wires, ignition top, and rotor have been introduced. Further data from the client showed that the truck fizzled the more regrettable in drive, not overdrive, at light to ordinary journey around 2000 rpm to 2500 rpm. The following test drive showed that he was correct and it was extremely repeatable. Anything outside that run and the discharge failure went away.
