Thanks a bunch I will give them a call tomorrow. Now another thing i found weird, when I drive and I try to let the car coast, it fails to do so, it almost feels like im stalling the engine, or that the break pads are rubbing, but there is no squeaking, what can cause this?

the torque converter will lock up on a slow down and if you touch the brakes it should unlock. the maf can be bored or if you plan on a good sized build you will want a little bigger one. i havnt done the research on the map for performance so im not sure were you need to start enlarging it. im thinking it was around 400 hp.

thats the way the converters work,,, if thats what it is. try touching the brakes just a little and let off. you should feel the converter disengage. could be a brake dragging.
no a bigger maf right now is not gona help.

what rpms are we talking and at what speed? are you sure its going into overdrive? shift up through the gears manually and see if its shifting four times.

if the maf is bad you should get the new maf in before doing anything else. it may be messing with the converter with bad info or the system is staying in limp mode. the valve body may have something to do with whats going on as well
