Changed IAC ,Plugs, wires, changed pcv with tube what the hell is going on.. It seems to help but i am so frustrated cause there are no trouble codes

Did you put a CAI on it recently?

You might want to inspect your charging system. That means the battery, alternator and anything else involved in that line. It might be your alternator that is falling off on you. Just take it to any auto parts store and they can test your battery and alternator right on the spot with everything still in the car. If it's not that, when was the last time you had your fuel filter changed? Seeing as how you had all the other parts replaced or checked those are the only things I can think of at the moment. I am sure others will chime in to help out and lend their experience as well.

i'd say fuel filter. not alot of places even bother to check it.

Vacuum leaks, anything in the serpentine belt system & it's driven accessories that's not spinning as freely as it should....

heck, if you told us the brakes don't feel right as well, the brake booster could have failed & caused the vacuum leak.....

Long list of possibilities...

if you give out more symptoms, like just when it dies - whether it runs rough or not - etc.. Then someone might be able to guess closer...

AT or MT? Need more information. If it is the AT, you might have the TB problem, and need a new TB which also replaces the TPS. The TPS for the MT is available, but the TPS for the AT can only be purchased with the TB.

Have you ever changed the fuel filter?

In order to check your voltage while the vehicle is running, use the electronic odometer trick: key off, press and hold the trip odo reset button, turn key on, continue to hold button until odometer reads [test]. Release button, now each time you press and release the button you'll scroll through one of 30 test functions. You will remain in test mode until you turn the key off. Find the function that looks like this [bat 12.1]. The actual voltage there is typical, and yours could be different. Now, turn the key to start the car without turning the key to off. You can now monitor your voltage while driving. Voltages over 15v or under 13v are not good and the alternator or connections should be inspected or rebuilt as needed.

My 2000 zx3 Kona Edition

I am going to check charging system than if that isnt the problem i will check the fuel filter i believe its original. Other than that i believe it could be the MAF sensor or something to do with EGR valve being stuck open

^probably totally unrelated and a long shot. I think that's on an escape. However,might be worth a look to see if the MAF is dirty. My 03 svt stalls, and I've yet to find the cause as well. Will definitely be looking into this myself.
