P03000 random misfire
***problem solved...read to end of thread****
I think the guy that I bought it from said that it was pulling up as a 0301 but now it’s showing up as 0300 on my Ultra Gauge...
I’m fixing to start going after this misfire on the 03 D2 with 151K miles that I picked up on last week. First thing I’m going to do is clean the MAF and TB.
Then I’m going to check and change the plugs. So I have 2 questions:
#1 Should I just change the the plugs and not the wires? If so which plugs do you guys recommend? Ive heard anything from comparable basic Champions to Bosch Platinum+4 ???
#2 Would it be better to just change the plugs and wires? If so, should I just get the plug/wire kit from AB?
From what I can find on Carfax service records, the last time the plugs were changed was 01/11/2012 at 95,039 miles.
Any other tips would be great.

Today i cleaned the MAF, TB and the Idle Air Control Valve. Put it all back together and it purred like a kitten. Service Engine Soon light was no longer on. The only code that was showing was the 1412 code, which I was going to tackle next. So everything was awesome! For about 5 mins into the test drive. The misfire returned and now it throwing the 0300 code and a new 1300 code. LOL!!
Any ideas?
I guess its on to plugs, wires and coil pack.

OK, well I went with the NGK (7092) BKR6EGP G-Power plugs. They are pre gapped at .044 ..Should I run with that or gap them down just a bit to be in specs? I pulled one of the current plugs, its a NGK Iridium that looked in pretty decent shape but the gap looked wide.
Ive also ordered new 02 sensors and a new purge valve...
Going to try those and then move on to wires and coils if the misfire persists. Even if the problem is fixed, I Will probably do those anyway at some point soon.

Just a guess here but it could be in need of a carbon cleaning of the valves. Some use the seafoam but I don't. Try a jug of techron and see if that helps. Are your misfires all on one side? If so maybe it's a coil. That 1300 is saying that you are in danger of killing your cats.
Ive got the 4 02 sensors ordered, SAI solenoid and purge valve ordered ( for a pending 1412) for good measure. Next step will be coils and wires and I got a quote from a shop to do that cause I just don’t have time to do that myself right now. We’ll see how these plugs and 02 sensors do.
