Ok, Ive searched tons on of threads on idling hoping to fix mine to no avail. TPS is adjusted to spec, and Ive tinkered with both of the idle screws to get an ok idle going. Here are the symptons.

1. Idles at about 1500rpm, but once it idles for awhile it will usually just die.

2. If Im driving at anything higher than around 3000rpm and put my foot on the clutch to brake, it will die immediately.

3. When I start it after it dies when Im not rolling( or else Ill just dump the clutch to start it) it will idle fine for awhile, which leads me to believe that the engine warm-up is what is helping it idle.

My streetport was done with Mazdatrix templates so I dont think its the motor. PLEASE HELP IT DRIVES ME CRAZY!!!

anybody??

 

How many miles on the rebuild? Check for vac leaks? Faulty AFM? Clogged fuel filter? Check all the normal stuff

 

5,000 miles on rebuild. Motor runs good and puts out plenty of power. COmpression is good. No vacuum leaks, Ive checked alot.

AFM can cause this???

I havent thought about fuel filter yet, its probably time to replace it anyways.

 

The AFM can cause quite a few problems, swap it out, if it doesn't go away, try the complete tune-up, if it's still there, then you've got some more digging to do.

 

Swapped the AFM off of my parts car, and it didnt seem to help at all. Any other ideas. I dont think its a clogged fuel filter because it runs strong when its going, it just wont idle good.
