My son and I have just acquired an 84 GSL (12a). It is stalling in deceleration and I realize it must be a problem with the anti-afterburn solenoid valve or the coasting valve. Any tips on resolving this problem?

Replace the AAV/ACV assembly. Mazdatrix sells them, but they are PRICEY.

Also, welcome to the Darkside. Check the FSM for your car, it'll help.

Also, please be sure to use the Search function. You'll be able to find some helpful info there, too.

 

Thanks, I did try a search but didn't come out with anything as useful as your reply. I have a Haynes repair manual, replacement is never suggested but it is implied. I'll follow-up on your suggestions.

 

Yeah, you're not the only one who's encountering that problem.

I'm getting a bit of a shudder during deceleration. I replaced the gasket around my AAV/ACV assembly, but that's because I previously took it off and the original gasket torn.
