1996 All Other Makes All Other Models Repair Question
96 lumina with 3.1
Anyone have any ideas?
Intake gasket is a possibility. I would get a bottle of throttle body cleaner and clean out the throttle body. Be careful with this stuff it IS highly flamable. Do not start the vehicle until most of it has evaporated. See if this helps first.

Sounds like a good idea. But seeing as the problem with the RPMs and the coolant leak started at the same time I am inclined to believe they are somehow related. Is this possible the RPM issue being related to the intake gasket.
try checking the sensor on the intake because if there isn't enough air flow the rpm would do that and check if no water or liquid is on the sensor

Hmmm, have you also noticed a power loss that has conincided with this problem? Typically, when the intake gaskets on these motors fail, water sometimes finds its way to one of the intake PORTS and causes hydro-lock in the affect cylinder....which can bend the connecting rod. I have seen this many times. It has all sorts of indications, just depends on what happened exactly. Do a compression test. If you find a weak cylinder (and you'll notice it right away), chances are its' been hydro-locked. Bad news. Good luck.

But with that would you only see the power loss once it gets up to operating temperature. Seems to me that if I had a bent rod the power loss would be apparent at all times which it isn't.
Well I am back. Got the intake gasket replaced and all seemed well. But the power loss problem is back. Seems like when the engine start to get up to temperature I will lose all mid-range power. It is only happening when the motor is getting close to normal operating temp tho. And when the problem rears it's ugly head the temp will quickly climb the rest of the way up to normal temp. Engine will rev fine while sitting in park or neutral but as soon as it comes under load it's like someone is cutting off the gas, it just won't rev. I am going to have it in to get sparks and fuel filter replaced soon but would appreciate it if you guys had any other ideas.
