[rob doggy dog]

i am new to jeeps and i am going to pick mine up tuesday and the problem is the guy says it runs fine except when you come to a stop it stalls , he has replaced all vacume lines and now thinks it is the computer or a vacume valve of some sort , any input is apprciated,its a 88 wrangler hopefully a comon problem i can fix easily..i now some jeep geek has the answers also he says that when it is first running in the morning it wont stall,.. until its warmed up, 6cyl.4.2 thanks , rob doggy dog

I could be wrong, but wouldn't an 88 be a carbed engine, and therefore, not have a computer?

O.K. I TALKED TO THE OWNER TODAY AND SAID HE ALREADY TRIED THE CARB. CLEANING TRICK WITH THE IDLE TUBES THING AND THAT WASNT IT. ANY OTHER IDEAS

I don't know if is the same in a 88, but a friend's 87 has a computer (that most regular mechanics didn't know about) under ther windshield washer resevoir. It was a source of similar problems.

thanks for the info i talked to autozone and said if i bring it to them they can test the resistance on it and tell me if it is bad , but i am going to start with that little black box called electronic ignition control module located under the windshield washer reservior, thanks for the input

Well $14 later and about 2 hours , i rebuilt my carb and it idles fine the venturi tubes were clogged , the ones you see when look down the carb that have brass looking ends , they looked clear but actualy were just built up in that same shape just smaller hole , also it passed smog! ,i did have that elect. ignition control module tested at auto zone for free it only takes a minute to remove the 3 screws from under nieth the driverside wheel well below the washer fluid tank , thanks guys!!
