Most of the time I need to put and hold my foot down on the gas pedal to start the motor.Wondering if the erg valve could be the blame? 89 f250 5.8 fuel injected. Starts great when cold start.  I have a new throttle position sensor , didnt see a way for it to be adjusted

Response:

It mabe new but was it setup properly. there is an adjustment on them.
It’s called Preload and dont hold me to it but I think it’s 1/16 of an inch. It’ could be 1/32.

I have a 1994 GMC Sierra, 2500 long box truck. 8 lug wheels. A friend of mine has some wheels to give me, that came off a Ford truck. The bolt holes measure the same, but the hub hole is bigger than my GMC hub hole. Will this matter, or will the wheel line up alright with the lug holes, instead of running on the hub?

Response:

1) They WILL work. I’ve cut the center out of GM wheels to use on Dodge and Ford.
2) Should probably work.  Make sure the hub is far enough out board to clear the brake calipers on the front.

Have a 98 Saturn DOHC 5 speed. Radiator fan will not come when hot but comes on when AC is used. I replaced the temperature sensor and connector but still no help. The “check engine” warning does not come on. I replaced the temperature sensor and connector. I also verified that there was 5.0 Volts measured at the sensor connector. I allowed the engine to idle until the temperature gauge was somewhat past mid range and coolant (now water) started bubbling out the tank. I turned the AC on and in less that 2 minutes, it had cooled down to near normal. What next?

Response:

Try using a paperclip to short the two terminals of the coolant temp sensor together. If the fan then comes on the problem is with the sensor or the coolant is not contacting the tip of the sensor.
