you won't believe this...i put the LFP TB on my wifes 05 using her pieces (TPS switch and throttle motor assembly) to swap out with on the LFP TB...it idled like it was nobodies business....so i trade from her car to mine still using the parts from her car...now my car is running like new! i then take the stock TB from my car and change it to hers...hers runs great...i have no idea what fixed the problem, but now i am in business...i think the TPS from my car may have had something to do with the rolling idle problem..i guess i will never know....

 

i am having kind of a similar problem with the rolling idle, but it is intermittent. i am going to go take the spring out and put it back in again.

 

I did not have all these problems. Mine worked OK.

 

i removed the motor, and the spring, and re installed it. i have the spring set at the 2nd click where it will stop. SAME PROBLEM!! i have to get this fixed, i love the throttle response but this is so annoying!

 

well its a little better now, but when i let off the gas it will sometimes surge up and down a little, usually about 3 times, then go to normal idle. i am going to have to mess around with that stop screw some more.
