I have a 2001 Isuzu Rodeo w/ approx. 90,000 miles. I originally had a check engine light come on and then within the past week my transmission light would come on and the engine would lose RPM's and almost stall when I would hit bumps in the road. Sometimes it has stalled, but starts right back up again without a problem. I am not sure if I have a transmission problem, a fuel pump problem, or even an electrical problem. On a diagnostic, I get a P0176 code which says "fuel composition sensor circuit malfunction". I'm not sure this is really the problem since I don't get the transmission light problem while in park and while testing the diagnostics. Has anyone had this particular problem before and can anyone provide some guidance?

Please let me know what solution you found.

I have a 2001 also with about 88,000 miles doing the same thing our mechanic was at a loss for the answer nothing appears on the diagnostic code in our case. We were
told it might be a torque convertor on the transmission. I will need to take it to an Isuzu dealer was his suggestion. Please post any additional information you find.Thanks
