I'm having problems w/ my truck. My truck runs great when I'm in idle I can give it gas and it revs up good but when I put in drive and begin to go it's like it chokes out, i'ved changed the fuel filter thinking maybe that would take care og it, then I checked my plugs and wires, nothing has taken care of the problem, could the oxygen sensor be bad or fuel pump getting weak? It's a 1992 chevy 1500 pick-up w/ 189,000 miles v-8

Well you did the first thing I would do is change the fuel filter, Also how long has it been since you had a full tune up done. I would recommend getting youre fuel pump pressure test done.

If it was my oxygen sensor or throttle positioning sensor wouldn't that throw up check engine light? I'm trying to do this w/o buying un-neeeded parts kinda tight on cash right now and really don't have the money to do a fuel pressure test

Well if the oxygen sensor or throttle positioning sensor have failed, You would get a check engine light on. You could buy the fuel pressure gauge unit for about $12-$20 at youre local auto patrs store, Least then you can tell youre not spend big money on parts.

The CEL/SES/MIL works in a mysterious ways.

Read below:

Riddle me this:

A saturn 1.9 comes in with an evaporative code.

Why would a engine coolant temperature sensor solve the code?

We know that the sensor is an infamous problem with cracking and creating a mirad of problems. The Bad sensor can throw a wrench into the evap monitor. The computer thinks it is in the proper temperature to run the evap test, when in reality the temperature is in the wrong range. Therfore the test runs at the wrong time picking up a condition that is normal for the correct temperature. The monitor test fails on a good condition and sets the evap code.

Take the advise and get it done-you don't want to be in no man's land if it decides to quit on you.
