2001 XJR Code 400

I get error code 400 EGR only if full throttle is used. Any ideas why or cure?

Don't use full throttle.

JTIS all refer to the EGR valve, blocked, stuck or broke.

I don't have one on my car but the JTIS R&R procedures do not look at all difficult. If you don't have JTIS it is available as a down load from here:
