I have a 2000 Millenia S with approx. 160K or 100000miles on it. Have owned it since new and have had all maintenance done at the local Mazda shop. It has given me no trouble until this week. Just had it in for a major maintenance step. Replace plugs, timeing belt etc. etc. Car ran perfectly before taking it in.On the way home after the maint work was done, the car stalled. Only did it once so was not too concerned. Two days later the check engine light came on while on the highway.I called Mazda and they can't get it in for a few days. Now it seems to have a real lack of power and I get the odd stutter when the car is first put in gear and before I apply any gas.Does anyone have any ideas. Could use your help......Kim

 

Maybe a loose vacuum hose, there is a plastic T on the passenger side toward the firewall under the removeable intake runner that commonly crumbles from heat. If he touched it it probably broke. Or a loose vac hose/wire or timing belt off a tooth would do it.

 

Thks, will check the belt and the connector. Just seemed a little to coincidental right after the maint checkup. I dont like coincidences.....Kim
