Hey guys an gals. my2000 3.9L is having some problems. I recently switched out my tb with one off of a 5.9 from a98 ram. It idles at 1100 after start upand after driving it a couple miles the idle will sit at 1500! its killin my gas mileage! ive read how i might need to switch tb cables too but i didnt do it. instead i sawed of the metal pin it would go under and it opens it just fine with a littleslack left over. O AND the pedal is really tight on start up. idk whats going on but i dont want to take my baby to the shop. please help fellow owners.

change your throttle cable.........

 

whats wrong with the v6 (not to sound like a smart a**?) I mean it has the same amount of slack as when the v6 tb was on

 

Ok then where can i get a v8 cable?autozone and o reillys do not have em and they are the closest stores to me

 

sounds liek a vac problem...

 

could the gasket be a possibility? and also how do i handle a vac leak?

 

did you look at the IAC valve ( Idle Air Control), could be gunked up with all debri, what condition was the TB when you got it?

 

it wasnt bad at all looked new minus a little build up here and there i even went ahead cleaned it with brake cleaner.

 

does it sound like it's sucking air? if it is, change the TB gasket and make sure you tighten down the TB far enough. if you cant tell if its sucking air or not, go ahead and change the gasket anyway.

 

alright ill get a new one an try thatif it dont work then ill be back SOON! thanx guys!
