Ok first gear not to noticable but all other gears i notice that i have a bad 5.5k to 6 sometimes 6.5k hesitation sometimes it even backfires at redline it feels like i was WOT take my foot off pedal and back to WOT its that bad and its driving me nuts....I dont think it is the fuel filter and i run marvel mystery oil through it every month or so so what the hell is my problem??

 

I know someone has some idea worth sayin

 

Try looking at your ignition system.

Check your TPS

 

I had a very similar problem. Playing with the safc seemed to help. Then I blew the turbo, then the motor so.... Problems like this are why I'm going standalone.

 

no my cars ignition is fine tps is fine i know the specs and they were right with a multimeter

 

My car did the same thing..i checked the TPS, ignition, and fuel systems...turns out i had about 5 vacuum leaks that where making my 7 run rich.......after i got that fixed i ran great....;o)

 

i just did a silicone vacuum job
