I have a 1995 Chevy Z71, The last couple of days it has been stalling, Or it is hard to start, Or it willdie if I turn on the A/C when it is at idle. I replaced the fuel filter,TPS, PCV, Check all my connections, Then it will smel rich. I still have this problem. The fuel pump is pumping fuel to the injectors,What sould I try next??

what about the mass air or does a 95 even have mass air. If it does check it a little piece of lint will make a mass air trip out. also the MAP sensor can make it hard to start and smell rich.

if you want to try just throwing parts at it I would try an ignition control module I have had the stalling thing happen to me like that and the module seemed to fix it. I would personally take it in and have it diaged if you have tried what you know and nothing worked. but thats just me :D

You should check the battery with a meter. The truck isn't going to run right if its not running at 13.5+ volts. Any strong draw is enough to mess up the firing (like when you first start the truck or use the AC).
Just my 2 cents

It sounds like the IAC is dead to me. Do you have a check engine light on? If so, figure out the code and that will give you a hint.

A 1995 is TBI so no mass air stuff...
