On my way to work last night ops went bad and lost lp. Read and post and jumped 12v to f terminal pump worked and made it home. I noticed that the truck was running on high idle pushing at lights could this be because i was rumnning off the relay and not the ops? thanks 1995 k2500 suburban 6.5l f motor

Jumped LP relay should not effect idle. Check for codes. How high was idle?

Does it go back to normal if you put the relay back ?
Check the CTS (coolant temp sensor) the sensor on T-stat housing. If this one fails, the PCM thinks the outside temperature is -40°C and revs the engine.
