PLEASE HELP ME
my mazda 1987 starts fine but wont idle. It has a new computer and leading coil from mazda and a new engine from atkins. when it starts it goes straight to 3000rpms. it sits there for acouble seconds then falls back down. it never stops to idle and then dies. if you give it gas it will keep reving up. if you keep the rpms above 2700 to 3000 it runs good. not great but good. a little back firing and kinda sounds like its off timing. i also jst put a new fuel pump, didnt change anything.
Thanks CHRIS

 

do you still have your emmissions stuff on???

 

btw search bar works great

 

So does it stall if you let it sit there or just idle high?

As of right now, no not really.

 

Turbo or n/a?

 

There is a good article on idle problems in the FAQ. I would start there.
