Alright. So after replacing the starter on the jeep yesterday and having it now crank 100% of the time, I'm on to the next problem to be solved. Stalling when idling.
(1994 Jeep Cherokee Sport 4.0 ManTrans)
So on my brothers cherokee, he keeps the battery terminals OFF the battery posts to keep that mysterious electrical gremlin to stop draining the battery. (The terminal clamps soon to be replace, the new battery put on has posts that were smaller, so its been over tightened and "bumped on" with a hammer one too many times).
Firstly, the jeep idles around 13.9 volts (tested with my multimeter), with about .2 volts either way, at about 80F. Is that within spec? I'm not sure how accurate the dash gauge is, because that says it never goes above 14 even when driving, and doesn't change with rpm speed does.
Secondly, would constantly leaving the battery off the posts, resetting the ECU constantly, cause the ECU to have problems? When It turns over (and it turns over well now) it idles around 900rpm, than dips to around 4-600 (bounces as it fights stalling). I've never owned a car with a computer this intelligent lol, so I wasn't sure if constantly reseting would cause it problems as I can't imagine it would.
After dipping down for about 5-10 seconds by itself - it revs up to 3000rpm, than slowly comes back down to around 900rpm. Than goes back to choking, and repeats. Its about a 50/50 chance of it dying when it starts choking, and thats where the problems lies.
Battery and alternator both have been tested at autozone to work fine. But than again, the folks at autozone aren't the best at what they do
So I'm going to head over to try and rule out the alternator with my MM (if possible, will research that aspect myself here).
I don't have the cash to be throwing in parts to see which one fixes it, so it will be more of a diagnosing each thing that can come into play with the problem, where lies you guys, as I haven't had much of a chance to work on jeeps til now.
Fuel filter recently replaced
Starter recently replaced
fuses checked and replaced as needed
Some sea foam was recently put in as well as fresh gas
I'm assuming we have good spark or else it wouldn't drive very well when its going right?
