My Mazda 323 F is driving me mad and I might have to scrap it. I have taken the car to the mechanics and they have changed spark plugs, leads and coil packs. All on separate occasions and all costing a few quid. When coil packs were changed the car didn't loose power for long period. But now its doing it again.

When they plug it into a computer the readout either says its fine or it cant read it.

For a while (2 years) the lights for the airbags have been on and that doesnt show up on computer reading.

Any suggestions?

  • Welcome to Motor Vehicle Maintenance & Repair!It seems you've asked several questions or possibly are considering disperate questions here ... could you edit your question and clarify exactly where you're going with it? The airbags will require a different reader from the standard OBDII reader (requires the SRS reading capability). This may be why you're not seeing anything about the airbags. If the other part is about the coils or it running properly, you've not stated your exact question. Please edit and put further information for clarification. – Pᴀᴜʟsᴛᴇʀ2 Dec 26 '18 at 20:44

Intermittent problems are a nightmare to diagnose-hwever, as there are 4 plugs, 4 coils, i would doubt all 4 fail at the same time-however, there is one fuel pump and i would suggest this may be the area to look at as if this failed, it would lose power-could be a loose connection etc...
