Default Engine Stalling

Welp thanks for everyone's help. I spareyed around each injector, between the intake manifolds, with carb cleaner, and nutting at all happened. I checked every vacum line, and there good. This car has a mind of its own, some days it runs great, other days it runs crappy, is there anything else i should check, should I change my 02 sensors. Im desperate

thanks

ok to reset the computer pull your ground cable off before you go eat dinner or something so it sits for 20min or so, reset the tps and see what that dose.

If it dose not help, pull your pvc valve out it is located in the lower manifold all the way in the back between the fire wall and the manifold. it should rattle when you pull it out.

Then like stanglx2002 said clean the iac and the maf.

the IAC in on the front of the tb and you take the 2 bolts off and clean it with carb or tb cleaner and get a new gasket for it and put it back on. The MAF the sensor between the intake tube and the fender tube on your CAI. Unscrew the sensor and be careful with the wires and scray tb or carb cleaner on the wires and use a Q-tip and lightly clean the wires off. Its a good idea to just replace the PCV valve and screen that is in the lower intake behind the upper intake. After you have done all of this reset the computer
