Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. If evidence of arcing can be seen on the inside of the spark plug boot, new spark plug wires will be needed.

1991 Mazda 626 Reviews
Bought the 91 626 LX in Oct/09 on the cheap and new I had to sink at least $500 to make it a decent running car. Replaced the driver side strut mount right away, and replaced the full exhaust system. Car runs grat after you figure out the idle on these cars. Burns about a quart or less oil each month, but I do lots of high speed highway driving. Comfortable car, solid and smooth running. The brakes fade when you depress them at high speed, so be careful! Overall a decent and dependable car.
Bought this car in Sept. 2009 for $500 and I have replaced the entire exhaust, 4 new tires, driver side strut assembly and brakes in the past year and a half. Good, dependable car, just keep the fluids up! Likes to burn a little oil and now I might have a small transmission leak (spotting in the garage). The steering is a little tight, not much power steering help. All in all this Mazda is good and cheap transportation.
