Question about 1999 Chevrolet Silverado 1500
On a cold morning I go to start my 1998 Silverado Pickup truck. It starts but will not stay running. It does this several times, but then appears to be OK except the Service Engine Soon Light is on. The light stays on all day. The next time I start it, it starts right up, but thelight is still on. The next day I go to start the truck and it starts right up and no Service Engine Soon light. Everything is fine for about a week then the same thing happens over again. Does anyone have an idea of what is causing the problem? It seems to happen only on cold mornings. The truck runs good even with the light on. I have a 60 month battery that is over due for replacement, could this be contributing to the problem?
If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.
