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.
