Engine Mechanical problem
1999 Chevy Tahoe V8 Four Wheel Drive Automatic 197000 miles
my truck runs great even when it freezing out but during cold months if I let it sit for 24 hours without starting, it will start cranking fast for a couple of seconds, then real slow like the timing is retarted and spitting thru the throttle body, then fast again. It continues this way throughout the cranking process meanwhile this is flooding the plugs and cylinders real bad so I have to pull and replace them. A couple of times I heated up the plugs and warmed up the throttle body and it fired right up. Could the air temp or other sensors be giving the pcm a wrong reading making it dump fuel( which is at 61#) if so what is the most common sensor to start an engine. Also the battery is fully charged and it never happens in the summer months or when the engine is warm
have the same problem?
