I'm Awesome
Ongoing saga of misery and dispair... (6 months later) 92 K1500
Okay, I have a 1992 K1500 suburban 5.7 TBI 150k mi.
I have very poor acceleration... I know my truck is a slug, but this thing cant seem to get out of its own way!
Also noticed that it is very hard to get going over 60-65mph
Things Ive already done:
I replaced the fuel pump/sender assembly <1k mi ago
Also did the fuel filter at the same time.
I replaced the wire harnesses to the fuel injectors because they looked burned
I also rebuilt the throttle body and replaced the injectors AND while I was in there I did the EGR valve... just to do it.
I replaced the TPS (was told it could be the cause of my no OD problem)
Other known problems... not sure if they relate to my poor performance
no OD (replaced TPS, had Cottman adjust the TV cable)
trans has late 2-3 shift and is sometimes hard shifting 1-2
Burning a little oil sometimes...
low voltage, possible bad battery or alternator... havent checked yet
Accelerator pedal seems tight? cant see where it could be binding at all, but it requires a lot more pressue than any other vehicle Ive owned including a 93 K2500 6.5, and a 96 3500 box van (5.7 vortec)
The effing box van gets going better than my Sub... wtf?
Thanks!
