BP starts for 30sec. then dies...

[mazdamx3freak]

i just bought a new mx3 BP and it drove fine for 3 days and now i go to start it, it idles for about 30sec and then dies completely know matter if i try to give it gas or not. I and getting spark and fuel and compression is 185 across the board. I also am getting a CEL for IAC but i tested it with a multi meter and its getting 12.3 ohms which is in the normal zone so what gives????

Is your MAF/VAF plugged in?

[mazdamx3freak]

yes all sensors are pluged in

[mazdamx3freak]

could the IAC cause this behavior? and is there any other way to test if its good?

[mazdamx3freak]

it does seem like if the MAF is bad by the way its acting but theres no cel for it and its pluged in . and does a maf just go out?

[mazdamx3freak]

Check for leaks in the intake air tube....

Check for intake leaks, especially on the bottom of the hose, check the vaccum hose on top near the throttle body.
Mine car had the same problem so I unplugged the IAC and it would start and run, but run rough when I gave any gas. then I unplugged the tps and it ran better! lol but I also had to swap the tps sensor when I put a Jspec BP in my mx3. now my iac works(rewired and cleaned it lol) but I still have the tps unplugged and have been driving around with no troubles, just slightly lower mileage and worse throttle response. Ive tried everthing i can think of to get the tps to work, including rewiring the original mx3 sensor, but the car still wouldnt run right.
good luck!
