FIL has a LB7 with a Juice/Attitude. The EGT's run normal in drive and cruising down the road, accelration, etc. When he comes to a stop and puts the trans into neutral the EGT climbs to 1200 but the motor doesn't seem to get that hot. Any ideas? I'm sure it's nothing but don't know how these systems react when an injector is going/gone out. Is the thermocouple in need of replacement? Thanks.
