oh yeah car sat from nov till now and wasn't started once

 

What all was apart? I had the same problem- i had a broken TB gasket. Take a can of carb cleaner (its what my mech did) and spray it around the TB, when the engine starts to die you found where your vaccum leak is.

What year is your car? I think the 93-early 95's all had plastic/paper ones. They now have a metal one that never needs replacing.
Hope this helps.

Damn thats a ******* high idle!Please tell me what it is when you find out the cause because in a few days im buying the FD in my avatar.Thanks and hope you solve the problem bro.

 

Don't forget to check the cruise control cable as well... might be holding the throttle open too far.

 

thanks guys i had the upper intake manifold off and took evrythgn off of it to make it shinny .
my car is 93. what is the tb throttl body ?

The throttle body is the part between the UIM and the intake elbow. The throttle cables are attached to it. Make sure they have a little bit of slack (the cables that is).

 

I think that question was supposed to read, "what is the TB, is it the thottle body?"

But anyway, a couple of other people have had this issue recently and have found that the cruise control cable (as spurvo suggested) was being pinched between one part or another, and causing the throttle to remain open. Take a look at that too.

 

check the idle air screw thats on the top side of the throttle body..

 

I had a high idle on my FD for a bit... it was a thermal wax rod... just wore out.. replaced it and all was good.. my idle was sitting at 2500rpm just out of no where btw...

 

i accually just had this problem on my car. I had some clutch work and the mechanic accidentally caught the throttle on something and it was idleing at 5000 rpm, like others have said, this is most likely your problem!

 

think the meechanic figered it out he didnt' have the mazda book to look at at first and he had the tps on backwards instead of the plug facing the driver side when u look at it it was facing the pass sided so i find out tommrow if it is good to go hope so. but thanks for all the help guys.
