Hey just curious but did you test your IAC sensor? that could cause rapid fluxuations in your idle

 

Yup, replaced that twice. And also the TPS. No luck there.

 

damn then its gata be the tb i cant think of anything else.

 

Thats the general verdict with it, but senior fastman will not accept that there just might be something wrong with this one. Don't know why he's being so hard headed about it. He could send Bobby a new one to try out at least just to make sure, but he wont do that. Keeps saying the truck has to relearn the idle. Which is why I'm hesitant to do business with him if I ever decide to get one.

 

What are the other options for a TB besides fastman??

 

F&B but it will run you about $400 since its billet aluminum. I almost bought one ..... but $400 is alot, but their dyno chart is claiming about +14rwhp on a 4.7l Dakota.

 

Well it might be worth the extra money just to not have to deal with all the possible headaches from a fastman.

 

I think when Bobby talked to him, he said some people have issues, some dont and he cant explain that. Maybe a lot more do have the idle issue but just live with it.

 

well if you put the throttle body up to light do you see any light around the throttle plate? because i cant see the throttle body haveing anything to dso with that if thre IAC is what controlls the idle. maybe that screws not adjusted right

 

yeah i've got about nearly 57K and i'll be replacing the IAC, and mapsensor this spring when it warms up to just have it done...will replace all the coils sometime this summer as well!
