99 GT having some engine problems Options

[daazndood]

Hi folks. I have a 1999 hatchback GT thats starting to show some symptons of engine problems.

It has 108,000 miles, and just had a major tune up at around 106,000.

The problem is, maybe like 2-3 times a week, as soon as I turn the ignition, the car will fire right up, and almost immediately the RPM will drop to 0 and the engine will die. Sometimes it doesnt die right away, but the engine will struggle and the RPM will continue to drop to 0 and the engine will die anyways. This will happen over and over again unless I press down on the gas a little to keep the RPM up. After holding down the gas for maybe 20 seconds, I can let go and the car will idle fine and its all good from there.

Also, alot of times, the idle will be very very low. like around 400-500 rpm. I can feel the engine vibrating the entire car. After driving around for a little the idle will return back to around 1000 and everything will be fine. But sometimes if I press the gas too much too soon, the RPM will once again reach 0 and the engine will die.

any ideas what kinda problems I could be having? I would be very thankful for any kind of insight.
