WHAT COULD IT BE. PLEASE HELP. IT MY DAILY AND I GATTA GO TO WORK TOMMORROW. AND CAN SOMEONE SEND ME A WRITE UP OR A LINK TO A WRITE UP ON HOW TO REMOVE ALL THE EMMISSIONS.(VAC LINES) I'M SICK OF VACUME LEAKS. :bigthumbu ALL YOUR HELP IS MUCH APPRECIATED. THANKS
 
Does it idle and when you give it gas it revs up and on the way down it shuts off? May be idle air valve.
 
I JUST FOUND OUT THAT THIS CONNECTOR ON MY MOTOR IS BROKEN. WOULD THIS CAUSE THIS SYMPTOMS ???

Of I Fixed The Conector And Everything Is Connected. There Are No Visable Cracked Vacume Lines And And Everything Is Plugged In. Wtf Is Wrong With It. Still Having The Same Problem. The Car Starts But Then Dies. The Only Way To Keep It Running Is To Slam On The Gas And Then The Rpm's Rise Slowly. If A Press The Gas Slightly It Chokes. Wtf??? Please. Any Have Any Suggestions. Is There Anyone That Is Familiar With Ka That Could Take A Look At It. I Would Pay A Reasonable Amount To Anyone That Gets My Car Running. It Shouldn't Be Nothing Big But I Can't Figure It Out. The Motor Is Completely Stock.
 
Idle Air Control Valve, take it out from the back/bottom of the intake manifold, clean it put it back on, disconnect TPS (engine should die or lose rpm's) set the idle screw on the IACV at 700-800rpms, if you can with a timing light set the timing at 20 degrees 15degrees if SOHC KA) should be a mark on the crank with the nipple from the front cover, plug the tps connector back in idle shoudl raise and fall back to where you set the rpms at before. if problem still exists REAPLCE IACV. they ussually get gunked up and cause malfuctions. If this dosnt work you have a vacumn leak somewhere, ussually a very small hissing nose depending on the size of the leak.

if you dont know the notches on the crank are, the notches are like this first notch is 5 degrees then Top Dead Center then 5 degrees then 10 degrees then 15 degrees then 20 degrees <thats what you want to set it at on a DOHC KA.

Theres ALOT more added into this for diagnosing the problem like checking ecu for codes and checking to make sure the IAVC is getting power. but 90% of the time the IACV is gunked up or bad.
