One last problem and this truck is perfect!

Well, in my eyes at least.

So, all new sensors installed except O2 sensor.

New ECM installed.

Truck is running very well now except once it is warm, upon letting off the throttle, the idle will take a nose dive. Most of the time it will recover pretty quick and then have a nice idle. Sometimes it won't recover quick enough and trip the oil pressure switch telling the ECM to shut off the fuel relay. (This would explain why previous owner bypassd fuel relay and wired the fuel pump to a switch in the cab.)


I'm thinking it must be block IAV passages but wanted to get your opinions first. If census agrees, I'm just going to buy a rebuilt throttle body setup.

Thanks
