Thread: stumbling at low rpm

yeah but there has to be a fix minus the ecu im in the process of swapping to a de throttle body and new tps just for shits and giggles and get my cruise control back. also getting new intake manifold gaskets and re-adjust the iacv,re-ground the maf,and clean it ill keep it updated

Sounds very good. Just double check everything, air leaks, voltages whatever might cause problems. I might want to put the de throttle body back on also. Just better in all to me.

i think .45 is a go. Make sure your testing it right. Get her warm like i said. If it doesnt budge much than its broken. Go to the junk yard and pull one off a roller rocker sr, and theres actually another huge infinity but i forgot what it is. i can find out though, those tps's interchange too

i have tried everything.... if you search the forums you'll see it's been covered here on the dash and the original forum for years, its the tune. I read somewhere it has to do with cars in extreme climates detonating under those conditions, so they pulled timing to prevent it. JWT is aware of the issue and it was suppose to be fixed on their newer ecus, but it's still there, just let it warm up a bit before you take it out

Hmmm not saying your wrong, I had this problem with my stock de also. But it was just little errors for me. And ALWAYS let the car warm up

well i was referring to justinsdetailing not you, this is his thread right?

Oh no your straight bro, and yeah its his thread. Guess he should get a calum basic?

Well I advanced my timing to 18* and it took care of 90% of it

I have checked it all out on my car and every sensor is in spec...
i just let it warm up to about 150F and after that it idles and accelerates with no issues, it runs kickass!!!

til the next morning

seems to happen when ecu is running in closed loop...

Main suspect. How mant degrees is the computer reading at idle and throughout the rev range?
