with the engine running lift hood and lisen for a vacum leak and check all your vacum lines. if no vacum leak can be found then replace the idle air control valve.

I had the same problem and it turned out to be a big vaccuum leak, Do you hear a whistle or similiar noise coming from under the hood anywhere? If so, check all of your hoses. Mine was behind the intake manifold..

I had the same issue except my car is a 2002 it is your idle control valve which cost anywhere from 174.00-500.00 depending where you buy the part. try www.partgeeks.com i had my car checked out at madza and my husband is a mechanic between to two i have no doubts. Good luck.

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.

I think i would be inclined to look at the coil pack ,and the wiring for this where it comes from the ECU ,i have never come across this before but its possible if the ECU isnt passing the correct information to the coil pack to fire in the right order ,what about the crank position sensor wiring are they shorting somewhere ?' Have a good look at the wiring and if necessary take the black outer sheafing off to inspect the wires inside
