Transmission not shifting, Slow takeoff, TPS?, Check Gauges Light 1999 Jeep Cherokee
1999 Jeep Cherokee Sport (4L 6cyl auto)
So I'm driving to work and my gauges went crazy, my radio cut out, engine lost speed for a second, then everything came back except now it's like I no longer have a first gear and I'm getting a "check engine" warning.
I have been getting an infrequent "check gauges" warning for the past few days and just went through a bad fuel episode a few weeks ago. Ended up using quite a few bottles of injector cleaner and changed out some seriously carbonized spark plugs and that issue went away, but I suspect that the carbon and junk has built up and affected sensors and such throughout the fuel delivery chain.
Tranny has had zero issues ever and I'm hoping this is really just something simple like the TPS
Again, it seems like I have no first gear and is not up or down shifting.
Idle is a little low (about 750 to 900) for vehicle since bad gas issue.
Acceleration is really slow.
Engine does not sound like it's stressing though, just really slow out of the gate.
I have tools, but no test equipment and I'm ok with replacing a few things that are probably going to need it anyway, but I'm hoping the tranny is good. It's my only vehicle, so I can't afford down time.
What do you think is happening?
Whatever is happening, where is it located and what's the best way to handle it?
