2001 blazer 4.3 idles really bad
I have a 2001 Blazer it throws the random cylinder misfire code. I have replaced the cap, rotor, plugs, wires with msd, new coil, deleted cats, new O2 sensors, new distributor, new crank sensor, new crank, new spider injection. When truck is idling runs like crap and check engine is flashing. It loses oil pressure when idling will not get over 30 P.S.I. at wide open throttle. I thought it was the cam berrings so i took the engine out took it apart sent it to my local machine shop to have them installed he said there wasnt anything wrong with the old ones. But replaced them like i wished. COMPLETE OVERHAUL DONE because of the oil pressure but it still does it.
Any ideas please help love the truck been a mechanic for 18 years and have never came across something like this
