I have a 1992 9000, lately it has been bucking and stalling out during slow speeds. This has been happening intermitantly. For example it will be cruising fine at top hingway speed,when I slow down at an intersection this is when it happens. I shut the ignition off then turn it back on then I'm on my way until it happens again.;oops:

My '95 9000 Aero 5-speed has TCS and it was the ground strap to the ECU that casued it to stall after coming to a stop!!;oops:

Hooter valve is the most likely issue. Though made of cheapo plastic the stock part is more than up to the job. They do fail and the symptoms are as you describe.


Sometimes the little PCV blocking valve fails which can cause issues.

A dirty throttle plate can cause these symptoms.

The AIC valve is anvil reliable and although it might fail this is unlikely, extremely unlikely.
