(1) I would suggest someone scan the ABS system for codes. I Have an '03 silverado 2500HD Crew cab, and it needs an EBCM (Electronic Brake Control Module) "ABS module". "Service Brake System" message on dash, ABS and Brake warning lamps lit as well. May be the R/F ABS wheel speed sensor, but what you described happen, shouldn't have caused damage to it.
(2) If the aftermarket rim and tire combo are larger than stock (larger overall diameter), then this may affect the way your PCM functions. You can reprogram the PCM to recognize larger diameter running gear so trans shift points and the speedometer and such can function properly.
I hope this helps.

It sounds to me like you have a vacuum leak or maybe a vacuum line connected in a wrong location. To find this if it's a leak, have a mechanic perform a vacuum test by blowing air through the intake. If there is a leak you will here air being forced out from the leaking location. Some shops also use smoke.
Hope this helps.

Most of the time when you run a fuel system cleaner in a engine that has not had a cleaning the sludge will clog the fuel filter. I would check the fuel filter before anything and if that is good, I recommend running a complete test on the vacuum lines sometimes if there is a leak in a vacumn line it will mess with the timing advance and cause the vehicle to behave different at certain RPM ranges

Was the car over heating before the water pump and head gaskets were replaced? Putting in a new Radiator will make it run even colder.and take even way longer than the one hour it is already taking to warm up.The computer in the car commands the engine cooling fan On/Of at a predetermined temperature.It receives this data from monitoring engine sensors such as the engine coolant temperature sensor.So if it is defective and the computer is not recognising the defect it thinks that the engine is running hot when it is realy running cold and will command that the cooling fan be on.Resulting in the fan running in 24-7 as you put it. If you want the engine to warm up faster and the cooling fan to operate normaly then I would replace the engine coolant temperature sensor and the relay for the fan circuit as well. If you need to talk to me further about this you can use the reply box below. Please let me know how this goes for you and I hope this is usefull for you. Good Luck and have a good XMASS.
