What mods do you have that you think you require a tune. Sounds like starting w/ the basics is in order. Cleaning the IAC and the t/b. Maybe you have a vacuum leak.

 

check your MAF is plugged in, clean your MAF with MAF cleaner, check/ clean your IAC and make sure its plugged in. check fro vac leaks with either a smoke machine or carb cleaner. check your base timing, set TPS between .6 to 1.01 volts, set base idle. and run koeo/koer and normal operating temp.


if you still have problems, let us know

 

Not to high jack but where are you going to college in SD? I'm starting grad school in Jan at SDSU.

 

right now I am going to a community college(Imperial Valley College) for my lower division and general ed classes, hoping to transfer to SDSU in probably a year

 

My car is having the same issue after i did my HCI. i recently found out that they make a part that goes between the IAC and the throttle body that lets you adjust/help the idle. Ford sells it. i haven't bought the part yet, but i plan on it.

 

you definnately need a tune. i tuned my full bolt on stock motor and it needed leaned out and made a substantial difference

 

really...so what exactly did this "tuner" do? modify your computers functions or did they adjust your car correctly to make it run right??

 

make sure the A/F ratio is within range throughout the rpm range

 

dang all these 5.0l

gonna be moving on to my turf

i live on just the other side of the freeway from sdsu~

 

nothin like spendin a couple hundred dollars to look at a graph.
