90 2WD 22RE DD. It's been runnin crappy forever, just been too lazy to troubleshoot it, cuz it still gets me where i need to be:flipoff2:

When accelerating most of the time I feel a definite loss of power, it sputters, runs rought at idle, etc. and sometimes its worse than other times. However, I've been noticing on hot humid days like today it accelerates way better.

I've always had a gut feeling it was a sensor, but I've replaced plugs, and swapped out wires and coil with MSD stuff from my other truck, problem persisted. Very strong spark comin out of each wire, timing's dead on. It's not ignition.

I'm pretty sure it's a sensor, but what do you guys think?

im too lazy to suggest anything like a fuel filter. i would rather think about getting work done than actually doing it

Step one insert dick in tailpipe.
step two have a friend start engine.
Step three have friend smell your junk.





























I don't know whats wrong with your truck, maybe its a sensor.
