3sgte hesitation Options

[rjbibeau]

i'm working with a 2nd gen 3sgte in an mr2 and when it's below 32 degrees outside or so when started it has a wierd hesitation when you open the throttle alittle bit almost like a rev limiter. but when i unhook the tps the hesitation goes away but soon as the engine is warmed up and the tps is connected again it runs perfectly fine. although when we first started the car up the tach was registering but not the right rpm it was under of what it was supposed to be. for example at like 4 grand it would read maybe 2. the car drives perfectly fine after being warmed up. i remember seeing something about the adjustment screw on the afm and it controls how much air is bypassed. would adjusting this screw fix the problem with the hesitation. any ideas?

alright i talked about it a little more with my gf and she said at cold engine when the temp is around 32 degrees it starts up fine but soon as you tap the gas just a little bit like as sliver and hold it steady it does a weird rev. i have a video that she can post a here later today. even when the car is still warmed up when she gets near that point of weird reving on acceleration just a little but it still does it. when she is decelerating to that point it does the same thing. i'm thinking this is a tps related issue. it's kinda hard to tell what rpm it is considering we have no tach.
