Just thought i would update this thread and tell you what has happened. It was the AFM all this time. Me and my bro done EVERYTHING mentioned in this thread even more!. I never suspected the AFM because it was a reco unit from UltraTune and when we took it in, they never said anything about it they just said they cant find what the problem with the car is.
Anyways, the car has been going perfect for a few weeks now and has even eliminated this really small hesitation that used to bug the hell out of me. It was like when even you will push the accelorator down from idle, it would kind of cut out for a SPLIT second but that problem was fixed by replacing the fuel preasure reg. Its so odd because we have had this car for around 8 years and has ALWAYS had that hesitation problem and now i have to get used to it not having the problem
So yeah, if you are having a strange hesitating problem, chack your fuel preasure reg
Thanks for all the help
