Hi Everyone,
It has been awhile since I logged on and I hope everyone had a nice holiday season. I must have jinxed myself when I said my truck runs great...make that past tense...it ran great. I thought I would get a tune up - changed the spark plugs, plug wires, distributor cap & rotor, both O2 sensors, and the fuel filter - all parts were OEM. Well, a mysterious electric gremlin showed up right after that tune-up.
My engine will literally "cut out" for a split second and the O/D light will flash on and then go right back off in a matter of seconds. I can feel the engine lose power for that instant - enough to give me heart failure - and then it goes back to normal. It was occuring at around 50-55 mph (usually while it was shifting), now it is starting to become more chronic without regard to speed or rpms - it happened at idle (once), but mostly under acceleration. It is almost as if there is a "blip" in spark or fuel delivery...like a cough or hiccup. It is almost like the computer is confused.
This never happened prior to the tune-up so I thought it might be the TSP; however, I had that replaced and the "blip" still remains. My next step is to check everything that was changed during the tune-up. My fear is that the tune-up may have affected who knows what
Has anyone else experienced this before or am I crazy?
