Looses power after 1st gear. Automatic trany. Replaced coil wires, plugs, IAC valve, fuel strainer, throttle position switch and still no power. Hesitant when WOT and in going up a hill looses power to 5 mph...
While driving, if I floor the throttle it backfires from engine and boggs until I let throttle off a little, then will run smooth but still no real power especially in overdrive....need help please!!!! Under 100k miles.
It's like it wants to go but something just isn't right. No one works on it around me, at all...so please put in lamen terms. I'm somewhat hood with engines but I'm not good at diagnostic problems....tks!!!
