Well my brother went to bring his truck to JDM for some tuning and and picked up my truck for me. Well he is heading back and once he is almost out of NJ the truck keeps stalling. Acts up the whole way home. Tranny is acting funny too with a Check Engine Light on. Light goes out after about 20 key cycles but later comes back on. So what does everyone think it is>??? Remember I got a new ProM Mass Air and 55LB injectors. Sounds like a Mass Air problem to me. Any help is greatly appreciated.

Now this is in no way a bash towards JDM, I would actually like to thank them for getting some awesome numbers out of my truck. I am sure they will take care of whatever went wrong. Also on a side note Jim bought me a new set of cats and I paid for the install. Which I thought was a great gesture. So I would like to thank Team JDM! -Mat-

 

I can't provide you with a possible cause but, hope all goes well!

I heard that ProMs dont work well in Lightnings....just an opinion from a specialty shop....

 

Thanks for the opinion. My brother is gonna scan it for me 2morrow since I can't do anything with this stupid leg. Ahhhh, another sleepless night. -Mat-

I've also heard of some issues with the ProM ?
I'd look there first, easy enough to try,
put the old one back on and check it out.
Also
Could the Chip be Loose ???

Good Luck, I know you'll figure it out

 

Yeah we are gonna look into the Mass Air first, I don't think we can just swap the stocker back on though due to the chip and I would think injectors being calibrated for the bigger the mass air. Not sure though. It could also be a loose chip, but I have never had a check engine come from a loose chip before. We will scan it and get back to JDM and see what Jim says. -Mat-
