hi, i have a slight problem with my 88 cherokee, its a 5 speed, 4.0 H.O.
it is not drivable at all..... when i start the engine it idles at crazy high rpm's, and if i push the gas pedal it just chokes, also it dies every once in a while.

anybody experienced anything like this?

Pull the codes...http://jeephorizons.com/phpbb/viewtopic.php?t=2719

My guess/gut instinct is TPS sensor...when mine went, the 'puter put the engine in "limp in" mode (where it guesses about data to compensate for sensor failure) and when that happened the engine raced like mad at idle....but those codes will confirm or deny that....let us know.

HTH
