Question about Cars & Trucks
I have a 2002 Yukon Denali and it has about 170,000 mi on it. But for over a year now, during cold weather it sputters when starting. It usually sputters for about 30 sec to 1 min then catches itself and will idle pretty high until it is warmed up a little. This morning, it was in the single digits last night, I went to start it and it did its normal sputter thing then was idling ok, then sputtering again then died. I went to restart and Reduced Engine Power when on and it would start and idle at about 1600rmp...no visible exhaust coming out of the tailpipe and no response when I pushed the gas pedal. I left it alone for about 30 mins and it started right up, no light except check engine light, it seems to be acting ok. Any thoughts as to what may be the problem? Like I said my car has never liked the cold...always sputtered upon start, in the cold only. Just last weekend we had to replace the fuel pump. Thought maybe this was part of the issue but apparently not.
Could be partially plugged catlyletic converter it will only get worse .could be the egr valve and or the map sensor three things a shop would have to check for you .

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

SOURCE: 92 yukon sputters at takeoff
is this a missfire? have you replaced the MAF sensor which is a common cause of this, if over 100,000 miles replace plugs and plug wires as well.

check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

It could be moisture yes, could be electrical if the wires and plugs are older they will crack and in humid or rainy weather they would be worse-or when they are cold.
