Re: need some advise on TPI not running well when warm

Computer uses many sensors to determine fuel supply and ignition advance. The coolant temp sensor may be faulty and causing problems. Or maybe an air temp sensor? A faulty knock sensor will also do the same thing. Obtain a TPI manual and troubleshoot those sensors with a volt meter or just replace them. Noisy electric fuel pumps are normal.
