Hi, I have a 1996 Hummer H1 turbo diesel. I have had more problems than I can count with this truck... Been towed 6 times during normal street driving and spent over $20,000 in repairs over 2 years. About to give up on my love...

My newest bug is I will be driving along. Come to a stop light, start to press the gas pedal and it will go all the way down and nothing happens. No engine rev. no go. I release the pedal and try again and its fine.

Well if making a left turn this could be pretty dangerous!

Any thoughts as to what could be wrong? Taking it to dealer is one of those things that you describe and they charge $350 to tell you they could not repeat the issue...

 

Have you checked you transmission fluid level. Mine was doing that so I made sure 1) on level ground 2) engine up to 190 degrees 3) fill it until it is in the crosshatches. I was surprised that it was less than 1/4" down from the crosshatches that it took a whole bottle.

If you are really low on T-fluid, pull the check plug from your transfer case. If a lot pours out then your transmission fluid is going into your transfer case. That means you have the vampire...

Would low fluid cause the gas pedal to not respond at times as I have described?

Regardless, All fluids are at normal level.

And I have already changed both shift solenoids in transmission.

 

After some research it might be this sensor on the gas pedal. The whole assembly is AC Delco part 213-2820

But I am going to try just a seonsor that might work too BWD - Accelerator Pedal Sensor Part # PPS1029
