Hey guys,

My car suddenly developed this odd "jumpy" iddle symptom. At times, it turns on, runs fine and suddnely shuts off and doesnt turn back on.

Edit: car does not turn on anymore!

It is a stock ka24e,
Manual,
Parts replaced: Coil, distributor, ignition module, fuel pump, fuel injectors
Check engine code 21: ignition missing in primary coil

Any help in identifying the culprit would be great.

My car has been working fine for several days now and i did nothing. Before this problem arose, i also replaced the temp sensor and vacuum.

Bump! After nine months of absolutely no problem, the problem returned.

Editeditedit! Car does not turn on anymore. I am getting code 21: ignition missing in primary coil. The coil, distributor, ignition module have been replaced. Wires, cap and rotor look great.

I'm stumped. Any help would be appreciated. Thank you.

Edit: does anyone know the difference between a Mitsubishi and hitachi distributor?

Bump. Still clueless.

Problem solved ya'll! Turns out my engine harness was extremely corroded. Signal was being lost somewhere.
