A forum for lovers of Infiniti's hot-rod crossover, the FX! In 2014, all FX models will be named Infiniti QX70, in line with Infiniti's new naming structure.

I have a 2005 FX45 with an intermittent problem. Certain times the car can be driven at no more than approximately 25 MPH. The service engine and SLIP lights are on.

Stopping then restarting the car temporarily 'solves' the problem and it will run fine for a couple of weeks before happening again. My mechanic connected his diagnostic equipment and says that the TPS (throttle position sensor) needs replaced.

Does anyone have a part number for this item or know of a good source? It must not be a common problem since I can't find anything about this by searching the Internet.
