Mazda 626 Bad Idle
I have a 2000 626 4 cyl 4 door car. When it is cool outside it runs great. When it gets over 90 deg. outside it runs bad. The check engine light came on and the code was number 2 cyl misfire. Only dose it at idle. The shop said Plugs. I changed the plugs, wires and coil pack. No luck. Next it the fuel injectors. The dealer wants $1200.00 for a new set and that is not installed. Any ideals before I wast that much cash.
