Needs Help with 89 Jeep
I have a 1989 Jeep Cherokee. It has started showing two predominant symptoms: !. it takes a long time for the ignition to start and 2. it is missing badly. I've changed the spark plugs. That didn't help so I took it to 3 dealers and called many more all of whom say they can't analyze the problems because tier computer won't work on such an old jeep. I need some help. I'm in N.W.Ohio.
Thanks ToganyT

Could be a number of things... You mentioned you changed the spark plugs, but when was the last time the distributor cap, wires, and rotor were changed? Could be a bad wire or the rotor could need adjusting.
If it's been a long time, I'd consider swapping them all out and seeing what happens. Normally it is best to diagnose the problem before throwing parts at it, but changing the cap and wires would be good for the Jeep anyway.
If that does nothing, I'd test the starter.

I'd test the starter. That Jeep is pre-ODBI if I'm not mistaken, so having it computer analyzed will be difficult and probably not worth your time IMO.
EDIT: A few months ago my '93 2.5L showed similar symptoms and it ended up being a couple broken valve springs. Valve springs rarely break, but my XJ is proof that it happens!

The computer on an 89 does not read all the stuff your "mechanics" are hoping to see. the renix fuel injection is simple and basic. do the basics.
Go to cruiser54.com and do Tips 1,3,4, and 5 before wasting any more time.
