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?

thanks guys I'll check for the codes asap and repost my findings. that tach is really wierd after the car has been warmed up a bit it has little more movement but not to the full extent that it reached redline even though the engine is at redline it's not showing up.
