To monitor Fan Speed on Car Scanner Pro: Header: 6C10F1 (Auto) PID: 22162B01 Formula: A*16 It always takes a good 3-5mins after cold startup to stop roaring in any ambient temperature. Must be the open loop fuel control period.

#55272 resonator is the piece to replace the existing pipe. The bends matches the hanger locations unless you go the custom pipe route. Hope there is enough muffler stub section to reattach and weld the new pipe. #55272 OD is smaller than muffler stub ID.

The intermittent shutdown at idle shortly after startup during driving happened to my truck recently. It was the cam position sensor on passenger side head that lost its place after driving a short period. Confirmed with tracking Cam actual phase angle PID on Car Scanner ELM. It causes the...

It typically takes 45 minutes highway driving at 50 mph for the oil temp to reach close to the Coolant temp at or above 200deg. Have an '02 with the oil temp sensor so I have tracked this. I would keep an eye on the new switch cluster reading under those conditions at idle for engine health...

The line closest to the strut that you have patched is the return line. That line is more suitable to repair since under less pressure. It is worth trying high pressure rubber fuel hose and pair hose clamps on each end to see if that will hold. You may have to replace that line later if the...

Just did this water pump replacement two months ago. GM OEM p/n 2512029 metal gasket is available at rockauto and was delivered in great (flat) condition. Glad I ordered it separate because the gasket that came with the water pump was all bent up. Used a star pattern when tightening bolts and...

As a long shot and preventative maintenance you can try to spray contact cleaner at the cam and crank sensor terminals to ensure the circuit provides clear signals. It worked for me to clear a slight glitch at idle.

When you swapped the donor engine into the '04 did you change out the cam phaser (cam actuator gear) or leave it as is? What year is the donor engine? I ask because the '04 models had the helical spline cam actuator gear which do not have a lock pin and depend on oil pressure to hold full...

Welcome aboard 'TOB'. Even as a mechanic you will find a wealth of knowledge to fix any and all issues from the folks on this site. I certainly have thru reading threads when the typical faults come up. I had occasion to browse more recent model suvs in the same mode as the GMT360 and was not...

Try disconnecting the charcoal canister hoses. Let us know if that works or not.

I was just stating at this point I don't think the purge or evap valves are preventing fuel from entering the tank. The last thing you should try is disconnect the hoses at the charcoal canister next to the fuel filter. It will allow the tank to fully vent so you will pinpoint if the cause is...

The Evap valve hose disconnected should allow the tank to vent to atmosphere albeit through the canister. With engine off the purge valve is closed so changing the purge valve can only help remove pressure (add vacuum) when engine is on. Plus it's not typically pulling vacuum at idle. You said...

@Stuntmanmike1977 have you tried adding fuel to the tank with the C101 harness unplugged so the pcm doesn't get any signals from the fuel tank? Or better yet, disconnect the battery ground terminal then try to add fuel.

The ohm meter is displaying kilo-ohms. Some digital meters actual show a small 'k' to indicate the ohm scale. .580k-ohms is 580 ohms.

Off topic but I found something interesting when filling up my late 2002 ENVOY (June build). The PCM fuel level% is accurate at low level but maxes out at 90% at overfull tank levels. The Dash gage is accurate at both low and full levels. I would think a full tank with correct fuel sender output...
