Engine Performance problem
1993 Chevy Blazer 6 cyl Four Wheel Drive Automatic
engine stalls for no reason. Either while driving or idling at a lite. Just like shut off key but restarts with no problem. Does not throw a trouble code. Have run with fuel pressure gauge and holds steady psi. Watched spark with led monitor but stalls with spark still fully available. May stall several times in 1 mile or may run for 1 week without a hint of trouble. Replaced complete exhaust system 1 month ago over plugged catalytic convertor.I am a hd. Mechanic but this has me stumped. Is this vehicle just sticking out it's tounge and saying you know nothing?
