Hey folks, ever since I installed my C&L upper intake plenum and Accufab 75mm throttle body, my '03 idles too high. When I start it, it will stick at 1100 rpm for 1 or 2 seconds then drop to 900 rpm and stay there. It used to idle at about 700 rpm before this bolt on. Any ideas? Should I take it to a shop and have the TPS adjusted, if that is possible? Thanks

Id love to get mine to idle around 900-1000. I dont like seeing my idle at around 700 which is where mine is at now and where yours was. It shouldnt hurt that car, plus it gives you a little extra exhaust note . If its bothering you though, you could take it in. If you go to Ford, they will give you crap since you modded it lol, but take it to a tune shop or somewhere and they could fix it for ya no problem. You may need a tune as well since the your mod could have done something to your a/f to make this happen as well.

Before you let Ford stick it to you try this thread: CLICK

You can easily check your TPS voltage yourself and adjust if necessary. Just need a voltage meter.
