Default What just happened?

Ok, so I took a little drive today on i-70, and the car was running fine, it maintained a good 75 mph. when I got off the high way, and accelerated onto the road, the car had absolutely no power. It felt like there was either no fuel, no spark, or no air getting to it, and that'* weird because I just gave it a full tune up. It'* fairly hot today, I think the Bonne told me it was like 91, and the car was running a little hot; around 210. Anyone have any ideas?

Were you by any chance turning right while accelerating, and if so, was your fuel tank 1/4 full or less? If so, then the cause may be the fuel pump sock problem that seems to affect the '92 models (including my '92 sse */c ).

If that'* not the case, then my next guess would be a possible TPS sensor or MAF sensor malfunction, either of which should trigger the SES light and set an error code.

No SES light, and I had more than a half tank. But you might be onto something with the fuel system..

Any idea the last time the fuel filter was changed? When you did your tune up I assume you did plugs and wires?

I changed the fuel filter, plugs, and the wires were fine.

When my fuel pump was dying, the higher the temps and the higher the fuel demand (like accelerating), the worse it performed. It would lose almost all power, and the boost gauge would flutter.

A dead or intermittant crank sensor will set the light off, if it'* weak, I don't know how it acts.

But please find the code retrieval method in Techinfo and see what you get. A code 17 (won't set the light) points to a dying crank sensor.

And get your fuel pressure tested when it'* nice and hot.

Also, possibly plugged CAT. If that was the cause, it will likely do it again sometime. Longshot, but keep it on your awareness radar.
