94 4.0 stalling now

[WhiteDevil1311]

I did take the IAC out today and its all the way out. Symptoms of a stuck open IAC jive with mine.

[WhiteDevil1311]

Today it started like crap. Garage smells very rich cat isnt making any noise when spanked

[WhiteDevil1311]

Got code 13. Replaced map with a mew unit. No fix. Comp never relearned idle. Its in the shop. Last i heard was it was showing a few sensors bad. Replaced a part inside the dizzy. Still diagnosing.

[WhiteDevil1311]

Its a 5v issue 4.3lxj. New map/cs/cps installed. .11v is all i got on the 5v circuitry

[4.3LXJ]

That would do it. Bad ECM or bad connection?

[WhiteDevil1311]

So far looks like a broken wire or backfeed ground to ecm. ECM is giving the readings it should the mech said. Possible 5v circuit isse in ecm but unlikely he claimed.

[WhiteDevil1311]

New dizzy new cps new cs new map installed. Broken wire in cps to cs harness. 1k in work

[4.3LXJ]

Ouch. That was a costly wire

[WhiteDevil1311]

Yeah but got a steel shaft brand new dizzy out of it. The duralast gold ones are worse then 90s holley carb baseplates. Just crap pot metal. The mech is a neighbor and he hasnt seen errr looked at the xj before friday when it ran as normal this morning he said he couldnt believe how quiet the motor is. Even his jeep guru is now saying its running bad due to the silence. I got 8/9 months of 55 hour weeks starting yesterday to bank some away and overhaul the susension and steering and do new floor pans in it. My great dane pointed out my cargo pan was rotten...

[WhiteDevil1311]

But yeah 1 wire. Replaced the sensors as process of elimination but atleast their new. 38 hours of shop time for just under 1k aint bad. Now i need to hook him up with some low volt landscape lighting for hooking me up.

[WhiteDevil1311]

I appreciate the time you spent man. It was a weird one. That single wire caused all sorts of 5v issues.
