The truck listed above has a 4.3 vortex engine. Truck is giving me check engine light. Replaced spark plugs, wires, crank shaft and camshaft distributor cap and rotor, MAP sensors and fuel pressure regulators. Cleaned the injectors to check for leaks nothing. Changed out the O2 sensors too. So, after driving it for say about 5 minutes it will give me that code again. Can't figure out what the problem is at all. Oh, I also changed out the EGR valve. Checked spark plugs for spark (good). I checked the spider for any ripped or damaged gaskets. Anyone have any ideas?
