yup just make them aware of the current issue before hand ,the dyno shop will get it all working right for sure, they will beable to tell whats causeing your idle issue 4 sure
i just got thru installing another tps on the car rpms seem to not be hanging as bad as they were, havent moved car yet to know if bounce is gone yet,what made me think it just may be tps is the autozone description of what will happen if not replaced mainly the tranmission shifting will be off

When all else fails,, smoke test it for vacuum leaks. Spraying WD40 on every thing probly wont find a well hidden leak. But smoke will every time.

What about the transmission shifting being off? Like how do you mean. I have an auto trans, and I put the hammer down the other day, and it shifted into my final gear at 110mph. That can't be right can it?

same her a auto, what it does is when it goes from 2nd to 3rd it will down shift back to 2nd while im on the gas just a little, but if im on the gas pretty hard doesnt seem to do it, i could see it doing that if i let off the gas but was on it steady

gonna do somemore test driveing later today to see how my issue is now with another tps on it

just a little update after driveing the car the bounce and surgeing came bk, so put oem tb bk on the car and remove the bbk tb and well ! well! the bbk tb was the issue after all no surgeing like it was doing at all ,gotta set idle a tad higher on oem tb because of cams but seems to be good to go , was talking with a guy that had a 5.0 had same bbk tb and had same issue, so i figured what the hell tryed it and wala !

any of you useing ngk plugs and what type and are they worth a dam?

WJL

it's my opinion that plugs are plugs, i know E3 and NGK all claim more/better spark even better fuel economy.

I think it's a bunch of BS really, if they in fact increased fuel economy or horsepower the car manufactures would be using them to improve their EPA ratings and reduce any fines they pay based on design requirements.

I have never put a set of plugs in my car and came back after a ride and said whoooooo, just saying Go Motor Craft
