i have a 92 se.. changed plugs,fuel filter,air cleaner, and oil.. it will drive fine for a 1/2 hour or so and then it hesitates when you kick it down it acts like its not getting fuel because the rpms dont go up when flored it just hesitates... if you continue driving it gets worse it wont go over 5 mph it hesitates... but for the first 1/2 hour it runs normal.. had it scanned it brought back low tps... no check engine lights come on.. and if it stalls it starts right back up... please help!!!

You can adjust your TPS. 92 was the last year for that.

For the hesitation, it'* very likely ignition, not fueling. Wouldn't hurt to check your fuel pressure both cold, and hot when it starts acting up. However, it'* likely a plug wire or two, or a coil. Sometimes when they heat up, they drop spark voltage. Do you have the Magnavox or Delco setup? 92 was a mixed year.

If you have a Magnavox, now might be a good time to consider an upgrade to Delco. But you should still do your plug wires if you don't know how old they are, or if they're over 50k.

Your O2 sensor is probably due by now as well, but typically will run you rich, not lean. Most times it'* not performance related, but rather MPG related.

its the delco... thanks for the reply!

when scanned the following codes come back
22 throttle position sensor low
38 brake switch circut (were ever that is)
36 transaxel shift control problem (what is that)

I had the same problem it sounds like on my 93 I had the tps changed and now it runs great.

is it possiable for a tps to act up after car reaches normal operating temp? or a blank spot show up?would you try to adjust old one or replace it with new at idol its at 0.24. im not sure of specs.. or is it some thing else? thanks for the help

Let'* find someone with the specs..have you test cold and once it stalls. It is possible for something to malfunction once it warms up. The expansion could be causing an issue.

If you test warm and cold..with different results, then a new one is probably in order.

i dont know why but it hasnt been stalling any more it just hesitates once it warms up.. (when you kick it down or wot) and its dangerously slow to get it up to speed..

changed the tps and it is still hesitating when you kick it down or wot... it hasnt stalled since about a week b-4 i changed the tps... any suggestions would help computer or fuel pump i dont know and i dont want to trow parts at it??.. thank you

im in minnesota were can i rent a fuel pressure tester?? ive tried auto zone they dont have em... i tried a couple local rental places.. THANK YOU!!
