Engine Troubles....

[Pissant22]

I have a 1994 Explorer XLT and it has been hesitating when i hit the gas, as if it was about to die. It has killed on me twice, once in a drive thru and the other time while pulling in to a parking lot, any ideas on what it can be?

Id start by checking for any set engine codes and repost

Have you replaced your fuel pressure regulator? Nasty little gremlins.

Sounds more like a throttle position sensor.

If it is a bad TPS, you'll get a code number 121-125. Probably will be 121. These things tend to wear out in the lower throttle ranges, and if you have a voltmeter handy, they are easy to check.
