Mazda 626 Sticking Accelerator

Jul 23, 2003 2 Replies

My partner's new (1998) 1.8i 626 has a sticking accelerator.



It is only stuck after sitting, usually overnight, and will then require a firm pressure on the pedal to unstick it.



I've lubricated the cable to no effect so then tried to operate the throttle directly. I found this to require some pressure to move the first time but after that it works freely, with perhaps a slightly sticky sensation when closed.



Could there be a build up of some sort of residue around the internal throttle mechanism which is causing it to stick? If so, is it worth spraying something into the air cleaner to try and shift it? What would you recommend?



Thanks, Chas.


I'm wondering whether the butterfly is closing slightly too much and becoming trapped when the choke tube cools and shrinks round it. Is it meant to close completely (idle air therefore getting in elsewhere), or should it remain open slightly?

Gave it a good toothbrushing with carb cleaner this weekend, seems to have freed things up.

Cheers, Chas
