SOURCE: problem with cold start up 1995 monte carlo v6 3.4

Two items to look at: Throttle position sensor, $45-50. PCV valve, $4-5. Either will, at times, produce problems with idling.

Ur coolant level sensor might need changing. If not, the circuit associated with the coolant level sensor needs to be inspected

Manual Solution for 1998 Monte Carlo z34:

Pull down interior design near button, it's all velcro underneath. The motor is silver and on the bottom of it, there is a white colored knob, that has a slot for a screwdriver. I believe to close it is counterclockwise. For this you will need VERY small screwdriver, and requires much force with a small one.

I poked a hole through the interior, and used a longer screwdriver. More torque and less pain on hands. Poking a hole sounds weird, but to be honest, it won't be noticed much.

I had the same problem on one of my GM vehicles with the 3.1L engine (which I assume yours has)

We could never find out what it was but replaced ALL the sensors, spark plugs, and spark plug wires and it got better, then eventually fixed itself.

If you have no check engine light on then its hard to pinpoint something like this.

Check MAF sensor first, then other air/fuel components.
