check to see if your TPS throtle postioning senser is out if you have more then 50.000 on it and never replaced it. i would even if you have less miles it wouldnt hurt. Things i learnd to avoid with out doing them from my mech. if you get on it hard DONT do it from a stop wait till your rolling first the ATX cant hanlde the power.

And DONT do any Nertrul drops. if you dont know what that is good. just drive it flush when needed. and Dont race it. the ATX intern parts cant take it and there are not any upgrades to help the weak parts but with proper maint. and not raceing it should last you a long time.

hope this helped. I just go off the phone with the mech whos rebuilding mine. and thats what he told me. and hes been at this for 30+ years and i only being 24 i take his word on it.
