major problem can anyone figure it out

[91dsmeclipse]

I have a 91 eclipse gs non-turbo and when the car gets fully warmed up the car's rpms bounce between 3000-2500 and when im at a stop the car does it again between 700-500 rpms and sometines the car dies and the car wont restart for about 15 min or so then it starts back up and runs fine until the problem does it again. The engine light goes on when the car rpms start bouncing it bounces like 3 or 4 sometimes more in a row does anyone know what this is i changed my vacuum lines my fuel filter,air filter sparkplugs,sparkplug wires, does anyone know thanks

have you checked all your vaccum lines? I am guessing it might be a leak in your lines... Spark plugs would affect voltage... so check that level too... but my guess is vac lines.

i replaced them already all of them and did a vacum test and it was fine any other ideas?

It would be nice to know what code(s) you get when it runs bad.

i dont have a scanner or anything like that

All you need is a $15 analog voltmeter. Digital won't work.

For about $5 at radio shack you can buy a 273-059 piezo buzzer and some microclips to read codes. Connect the red wire to pin 1 on the DLC and the black wire to pin 12.
