Question about Mazda 323

1 Answer

I own a 1992 mazda 121 and the engine is cutting in and out. When i press the accelerator and hold it in one spot, the revs go up and down, even when the pedal is pressed at one spot, the engine turns off as soon as i relese the pedal. The revs seem to drop very suddenly, and the engine cuts out. This has just happened all of a sudden, im not sure if it has anything to do with the fuel as i just put full tank e10 last night. When i started the car this morning and drove off, the car was running really rough, and seemed to feel as if the car was cutting in and out of power. When the engine turns off, it can be restarted, but the revs drop straight away and the engine turns off

SOURCE: my mercedes e300 (1989) starts and runs ok but then cuts out.

I had a similar problem with my 1986 300e , which got progressively worse until the car was no longer driveable, I changed out the fuel pump relay and the problem went away.

My1991 mazda 626 will not rev up over 3000 rpm


DO YOU MEAN WHEN YOU ARE ACCELERATING? Or do you mean sitting and reving the engine? If you are just reving the engine in park then the rev limiter is kicking in.

Sticky accelerator action Mazda 121


Yes it does. But I would clean the throttle body first by taking off the hose that comes from the air filter to the throttle body, held on by a steel clamp. Hold open the throttle plate and spray it down with a brand name carb and choke cleaner. Keep me posted please.
