Chevrolet Repair: Idleing, nuetral, scan tool

Question
Happy Holidays,
I have a 94 euro Lumina with a 3.1 engine.  The problem is when the car gets up to running temperature and sits at a light.  It will trip the check engine light and start spitting and sputtering.  Once you start off the light it straigtens out.  While @ the light you either  have to put the thing in nuetral or keep your food on the gas.  The light goes out when the gas is applied.  Also, I don't know if it makes a difference, but I notice the charging guage fluxuate when it is doing this.

Answer
Hi Joe, The first thing I would do is check the code that is in the computer. You'll need a scan tool to do this. The most common thing to cause this is the computer, but if there is a code that might lead you to a bad sensor. I know this isn't much help, but you need to scan the codes to start.

Have a Great Holiday        Mark
