Re: 91 2.8 only starts on full throttle
Parts that are new since installing engine are as follows:
oil sending unit, tps sensor, IAC valve, Temperature switch, thermostat, distributor cap and rotor, spark plugs and wires, fuel pump, fuel filter, MAP sensor. I have also started the truck and did a light tap test to ECM while truck was running there was no change in idle. Also did an OHMs reading on temp switch it is currently 90 degrees and I got a reading of 1507ohms on sensor. Seems engine has a bit of a lope to it when idling.
