What is causing my 97 mazda pickup to idle rough then die?

I would suspect a vacuum leak. At idle under high vacuum the air fuel mix is being leaned out until you have misfiring so bad the engine quits. The exhaust smells rich because even a lean mixture, if it doesn't light off, if full of unburned fuel. At road speeds, the vacuum is low so the engine doesn't care if there is a small leak somewhere. It is getting most of its air through the open throttle. Check all your vacuum lines but remember that even if every line is okay, it could still be leaking from an old cracked intake manifold gasket.

I have a 1995 Mazada 626 V6 and i had a simular problem. My mechanic couldn't figure it out. My boyfriend did the usual checks also, but 1 thing extra he raised the idle to 1100-1200 rpm's from the 750-1000 it was at...well since then no problem.
good luck

Please be fast about checking your fuel pump. It is not giving enough fuel pressure.

Cheers.
