1992 GMC Sierra

Question

My 1992 Gmc Sierra has this strange stalling issue.

The truck starts and runs fine with now problems.

But for some reason when say I'm comming to a stop at at traffic light the truck shuts off within the 0-5km/hr range.

 

A lot of times I can Put the truck in Park to prevent it from stalling but you have to time it perfectly and doesnt always work.

 

So once it stalls I can start it and drive with no problems.

 

I took the truck to Our Local GMC Dealer,

 

And after 10 days and $1500 dollars the dealer said it was a Faulty module.

 

They replaced the module and now its doing the same thing after 6 months .

 

This is leading me to belive it is not a module problem

Yeah, I hear ya Rob. I guess this one is better than diagnosing a "squeak" online though! :D

 

 

Just cleaned an IAC due to having the same problem ... but it was on a 27 year old Mercury Grand Marquis. Completely different design though - sequential FI, so only air going though the butterfly. '92 GM should be throttle body - basically a carb with 2 injectors on top squirting on the butterfly, so no IAC.

 

The ol' module aye? Did they tell you WHAT module? Sounds like a ripoff in progress .... :uhoh:
