What trouble code are you getting?
I don't know what the exact code is, but I seen it on the computer at Advanced Auto. Is said Temperature send sensor bad.
Also, the RPM's were at exactly 1000 prior to the therm housing being changed. When I picked my truck up, it was dead set on 500, and has idled there once warm since.
Have the coolant temperature sensor checked and tested could be out of specifications
That is one of the 2 that were just replaced. They actually replaced that one 2 times. Would it make that much difference in how my truck starts? Could and why would that lessen my idle rpms?
Clean the idle air control valve and also the MAF sensor with an electronic cleaner called CRC and see what happens
I will get it tomorrow and try it. Will let you know.
The ECT is an important sensor for engine performance as the wrong reading can result in the engine computer sending the wrong command to the fuel injectors.
Get another scan done and get the exact trouble code for me. Since parts had beed replaced, codes might change if other problems are causing it.
I just got home from having the code checked. It is P0117. Coolant temp sensor 1 circuit. I had them show me the part that would be replaced, and it is one of the sensors that was replaced less than 2 weeks ago, but not the one that was replaced 2 times. This is the one that goes to the computer I assume because of the issues with the truck. How does one go about replacing this without ripping it all apart? I would have to loosen the intake manifold, the upper radiator hose, the air intake,and probably the top of the therm housing. Is there an easier way?
