Well guys they(lexus) final got it right...it was a bad mass air flow meter....this was causing the car to bogg sending the ecu the wrong signal for the transmission to shift.. and OMFG,the car is like night and day from before!!i told my fiance that i was gonna drive it like i stole it right off the lot... i pulled and looked at the car so anxious to get in it and test drive it..well to say the least as soon as i started the car for some strange reason i was like,its finally fixed, i could just tell....i pulled out the parking lot after letting the car warm up...i nailed it out the p-lot and got sideways for about 40ft...i was like, ooh yea the beast is finally back...Man i am so stoked to have the car back and to have it run the way it should run and shift the way it shoould...before leaving mobile,alabama i ran around town trying to make it mess up and mis-shift or hesitate on the gas in between the gears..it never missed a beat!! Props to lexus for finally getting it right and fixed after 3 trips from pensacola florida....i was afraid to start modding the car before then except silent stealth cold air tube i have with the k/n drop in..., but now it is so on,i came home and ordered some headers,downpipe, and hotchikis springs..so for all you guys that followed this thread, thanks and this is finally a happy ending!!!
