95 tracker miss after warm up

[fixkick]

well while driving it threw the tps code... never done that... (hint they all do this old or over 100k miles)

Which code? 21,22,44,45?  there are 4 errors possible one sensor (device)

know that codes are live errors, driving and can in fact self clear as soon as the happen
even clear in 1 second.  (all are real, they never lie the ECU sees this and is always real)
that is why driving and logging , works best no matter how done.

on new cars 96+ we log to PC, laptop, and see IT ALL.every thing at once captured. (live sensor data and DTC errors both and lots more possible)

on this car it takes humans looking at the silly limp flashing and is only crude errors
means dead sensors, and can in fact be intermittent. (old cars do that, worn out parts or calibrated wrong)

TPS bad can cause TIP-in misfire.  (as in right foot tips in the throttle,TIP of foot)

There really are 2 TPS here (4codes) one is the throttle angle and the other is and  TPS idle switch.
both can case , tip IN,  throttle stalls, misfire or hesitation at any  (angle sensor )speed. (it is really TIP in lean out)

what happen is this ,  for TPS, errors. (ECU goes nuts seeing this error , running the engine,)
how does this work:?
easy.

The fact is that THE TV allows huge air flows into the induction with a super fast right foot worse case. (and rule one air does not burn)
the causes huge vacuum drop that the ECU sees way too LATE,  do to slow actions of MAF(16v) OR MAP (8V)
THIS CAUSES a super LEAN CONDITION,
but the designers know this and...
the cure is a TPS is fast as 90% of the speed of light, (the TPS sensor is that fast) and the ECU sees the foot fast and goes super rich fuel mix. to get full power and not a bog, or misfire. lean.
That is how all cars work EFI. every  one, do to the slow MAF/MAP. (
back in CARB days, Carberetter, the high speed accelerator pump did all this. instant rich fast foot. on EFI this is now electronic, no more Carbs.


the TPS on this car is calibrated by hand. if done wrong or the the switch is bad? ot fails and other effects told below...
the idle controls (late TPS) fights your right foot just off idle,  this can be profound this fighting. (gross hesitation)  and does not effect driving fast, ever. only idle to off idle transitions. The main TPS throttle angle part can fail at any speed, any TV angle can fail do to bad carbon inside, the TPS, (dead spots)

what code (of 4) did you get, all codes matter big time and they all mean gross error detected. as in Very important.

good luck to you.
hope you like my theory talk on how EFI works,  and some race cars only have 1 sensor, TPS, due to running on track mostly full throttle.
they run rich full time. for max power about 12:1 AFR  fuel mix. or in drag racing.

progress,  finally , with TPS errors, (no matter how long or short, all are KILLER BAD)

it also causes , FAIL safe for the duration of the failure,  and  super complex effects that. "ugly" on any 89-95 that
