Customer Question

I have a US 2004 xjr with code P 1251. Started after reversing out of a spot and shifting top forward. Went to forward and car lurched as if hit from behind. Check engine light went off and it went into limp mode. Shut off and started again, same thing. Left for two hours and it started and drives fine - just with CEL on. Any things to rule out first? Thanks

That code is for the throttle motor relay. We need to check all the connections in the engine compartment fuse box to make sure all are clean and secure. Let me know.

Also check fuse #24 (20 amp) in that fuse box. It should have power to it when the ignition is on or engine is running.
