Why does Mazda 323 1990 miss and stutter when driving?

Answer 1

lots of possibilites here,

1. bad fuel ( water in tank)

2. fuel filter clogged

3.distributer cap cracked/wet/oily

4.fuel pump about to go, or bad ground (under rear seat)

5.bad ground contact on engineblock from battery

6.worn spark wire/wires

7.bad plug/plugs

best thing to do is open the little black box under the hood in front of the wiper motor on the driver's side...it says 'diagnostic'....take a paperclip/wire with two bared ends/twist-tie what have you..and insert one end where it says GRD..and the other end where it says 'ten'.

Then while connected..get in and turn the ignition key to the second position (just before start) and watch the 'check engine light'...it will be solid for a bit, then start flashing a pattern if it has an error stored in the computer..

I will jump ahead as these cars have common distributer problems...if it blinks a series of 2 blinks..you have to replace your distributer.

good luck !
