My 99 Yukon Denali 5.7, starts and idles great, but sputters while driving between 40 & 80kms, codes p0137 and p0131. We know what they are tho

Did u change distcap..may be corroded inside. There r two sensors gettn low voltage. Sounds like the othr is not heating properly too. A data stream run at a private shop is really helpful

I have a 2002 Dodge Ram 1500 w/4.7L 98000 miles. When I start it up the rpms goes to 2000 and flucuates between 600 - 1500 rpms. When in drive the idle still flucuates between 500 -1000 rpms. Could this be...

Idle Air Control Valve, most likely.

Is the check engine light on?

you may have two oxugen sensors on your yukon. if so the oxygen sensor that controls that bank may be bad. from what you mentioned in your complaint, it sounds like it is the oxygen sensor.

I figured out what was going on. supposedly on ford rangers the Idle Air Control Valve (IAC Valve) goes bad. i got a trouble code looked it up and sure enough it is the IAC Valve. Under 100 bucks for the part

Overheating when outside temp goes above 90 degrees F

on GM vehicles they still use clutch fans and when sitting at an idle for a while the fan is not pulling enough air through the radiator and condensor so therefor the a/c starts to put out warmer air and the coolant temp. will rise a little bit. You could try replaceing the fan clucth and see if that helps any.

Most sensors will trigger the check engine light, however the TPS(throttle position sensor) or EGR Valve(exhuast gas recirculation valve) could be potential causes. Does this problem only occur at idle? Is the idle normal in park? Let me know and I can try to assit further.

Hope this helps
