Hey, 1997 Cherokee 4.0L Auto.

There's been a number of little things wrong, but I can't seem to pinpoint them. First, someday's it starts right up, idles, perfect. Later in the day, starts, but will die unless I hold the throttle, if I give it gas it will sit a ~700 rpm, but if I let off it just dies. I thought this could be the TPS, so I cleaned it, but still did it so I just replaced it. Well, the starter has been acting up also, randomly it just clicks when I turn the key. I am prettry sure that means the starter is gone, but then maybe a few minutes later it works. Ideas? No CEL or codes. Should the starter just be the next thing I replace? Then figure out the idle problem?

I have heard of the crank position sensor causing problems, but that didn't make sense to me. Anyway, thanks for your time!

Scott

IAC is your idle problem .

your vehicle wont run with a broken CPS

you could have a low battery , or the starter solenoid is dieing /bad wires .
