help!!

[STUGOTS]

I just changed my TB"s and put on smooth tubes and as soon as I did the car hangs at about 2500 Rpm everytime I let off the gas.

Any ideas???

So, you put on the big TBs. Oh well.

Sound's like something is sticking.

I'd take off the smooth tubes and see if you get the same hang up.

Disconnect the throttle cables one at a time and see if that fixes it.

Do you know how to do the cable adjustment procedure?

When it hangs at 2,500, get your foot under the gas pedal and raise it up. If the hang goes away, some adjustment to the return springs, or alignment of the two throttle bodies needs to be made (loosen the bolts and you can rotate them slightly).
If it doesn't go away when you raise the pedal, check the passenger side adjustment screw on the throttle linkage and make sure it's not holding the TB partially open.
The last item to check would be the stop screws on the TB's, but I doubt that's it.

Regards,
Sean

also just wondering can the TPS do this as well, im just asking because that took a hard spill?

You may want to check your AIC valve. I have disconnected mine for what ever reason and forgot to put it back on. It made the car surge and do irractic things, then I replug it back in and it idled normal.

its only when i rev the car and let off it doesen't idle at 2500 allthough the idle is a hair high but im wondering if that happends with larger TB's.

 

[STUGOTS]

Found the problem its my TPS the new TB's throttle shaft is too large for the TPS, it holds the TB's open when you let off and i called dodge and found out by the model numbers that the TPS i have is not OEM (damn dealer)it worked properly for stock TB's but not larger ones

 

[STUGOTS]

The stock TPS will work for 70mm TB's right?
or do i need to get a diffrent one?
