please help Stalling problem

[88eliminator]

Hello, I have a 1988 jeep comanche eliminator. It has a 4.0 i6 with Aw4 trans with 82,000 original miles.

 

I just put an all new champion 3 core radiator and put new battery cables on. I finally fix the overheating problem and drove the truck for a day and it drove better than ever. At the end of the day I went to the store and as I drove down the street the truck drove great, and as soon as I came up to a stop sign the truck dies in drive. I put it in park and it started right back up so I decided to head back home because the trucks never has done that before. on my way home it died about 2 more times only when coming to stops. I got home and decided to park it and try it again in the morning when the truck is cold.

 

This morning the truck started just like it does everyday so I drove it down the street and when I got to the stop sign it dies. This is when the truck is cold. right before it dies it sputters.

 

The tachometer stoped working two days before this problem so I don't know what the idle is right before it dies.

 

Any help would be awesome, Thanks.

sounds like the tps......Thats where I would start at a low cost point remove and clean IAC with carb cleaner might as well clean the throttle body while your in that location. But most likely its a TPS issue.  Does it stall if you say don't come to a slow stop but come to an abrupt stop?

[Megadan]

The TPS could definitely be a culprit.  Stalling like this is also a sign of a bad O2 sensor as well.  Sounds like a little investigation is in order.

Thanks so much for the advise.

 

I have not tried doing an abrupt stop but I have tried coming to a stop in neutral and it seemed to still die.

Ok so I bought a new TPS and just put it in the truck. I then started the truck and it started up perfect and idled fine. when I went to go drive it, it sputterd right away while I was in reverse. but still kept it's idle. It went into drive fine and as i gassed it and it cut out and died right away. The truck started back up and I put it in reverse so I can make it back in my drive way. It cut out really bad and died but I was able to coast back in the drive way. When I tried to start it up again it didn't start at all.

 

I checked the full pressure and it was good but other than that i'm lost because the truck will turn over but not get a good spark.

 

any help would be great. trying to fix it because its my dd and I need it to run before I go to school.

Slow down a bit here.

Did you adjust the TPS per my instructions?

 

Have you ever performed a throttle body cleaning? How long since new plugs, wires, cap and rotor?

 

Engine vacuum harness intact? Intake manifold bolts loosened up?

 

Also, I would click on my link below and perform Tips 1 through 5 before chasing any more rabbits down the trails.

Hello thanks for responding.

 

I have not adjusted the TPS yet, been away from the truck for few days.

 

I have never cleaned the throttle body, but changed the the rotor, cap, and plugs about 6 months ago and only have like 1,000 miles on it.

 

I just replace the vacuum harness about 3 month, and I have not yet checked the intake manifold bolts if they were loose or tight.

 

Thanks for the information and ill let you know hoe things go.

No I didn't change the plug wires because they didn't seem like a problem

No plug wires? 

 

They are part of the secondary ignition system and carry a high load. Factory recommended every 60,000 miles. We replaced them at the dealer every 30,000 miles because they tended to fail before 60,000 miles and irritate customers. What if the coil wire or others has small brakes in that graphite coated string inside?

Today I cleaned the throttle body and put on the IAC that I had just bought. I then started the truck and it started great so I drove it down the street and came to a stop with out stalling. I drove a little farther and turned around and noticed it was hesitating from taking off from a stop but would not stall. I started to drive it back home and I came to an abrupt stop and then the truck died. The truck usually starts back up but this time it would not start at all. I decided to unplug the coil wire and plug it back in and the truck started right back up. so I drove it back to the house and right before the drive way it dies again while slowing down. 

 

I decided to just replace the plug wires because the coil wire seemed bad. I just replaced the wires and it started right back up. I drove it around the block once and then I came to an abrupt stop, it didn't stall but it sputterd. I then came to another stop and it dies, but will start right back up. 

 

So the problem seems to be improving but it's still there. It now dies when coming to an abrupt stops, and it seems to be stalling now when the truck is starting to reach operating temperature.

Thanks again for the help.

My Tip 4 should not be overlooked. After reviewing this thread, a question comes to mind.

 

Did we not strongly suggest you perform my Tips 1 through 5 thoroughly? Coulda missed that with suggestions of sensors to replace right off the bat.....

found out my problem, broken coil. just put a new coil on and the truck drove perfect.

 

Thanks you so much for all the help. I will continue to go through tips 1-5, I'm just glad I fixed it. Thanks again.

Like a good ending to a bedtime story!! Thanks for the update. get to work on those tips!!
