It's been quite awhile since I've posted or logged in.
My '03 D II now belongs to my son. I'd been saving it for his first car, so it didn't get driven too often in the last 5 tears.

We immediately replaced a bunch of things, TP Sensor, thermostat, drive belt and tires

It's been running great - code free until this past week, he's been driving it for the past several months without major issues.

​​​​​ As I said, it's an '03 with 97k - here's the 5 codes that were new this week:

P0308 - cylinder 8 misfire
P0300 - random misfire
P1300 - catalyst damaging misfire
P0441 - evap emission system, incorrect purge flow
P0305 - cylinder 5 misfire, DTC Severity 2 of 3, repair immediately

I ordered 8 mm Magnecore wire set, 8 Bosch plugs

I replaced the plugs and wires when I bought it @49k miles.

SES varies from solid to flashing - it's been parked since this all started a few days ago.

What else am I looking at besides plugs and wires? I guess one of the coil packs could be bad, too. The P0441 - I don't know what to do about that one.

Any help is appreciated, let me know what other details are needed to help.

Thanks,

Matt

 

 

I did have a terrible time getting the factory fuel cap seated properly when I gave it to my son.

Tried a thin coat of white lithium grease, didn't really help, and finally the cap broke.

I had to order the proper cap, installed it, and it's been fine. That could have been an old code???

I'll try cleaning as suggested and see if the issue persists.

Thanks for the help.
