Hey, just looking for some advice as to where to start diagnosing a few codes. Don't wanna just throw money at it, so hopefully you all can help avert that! 🤣

2004 se7
140,000 miles
P1300
P0300
P0304
p0308

Service engine light flashes, even at cold start/idle.

I unplugged the MAF sensor, as in the past, the p1300 code has almost always been the MAF, and when I unplugged it, the engine stumbled, indicating to me that the MAF was probably atill functioning. However, when I plugged it back in, absolutely nothing happened, which I thought was a bit odd.

It appears to have the original grey spark plug wires, which I'll try and check for cracks/jumping spark, and was also thinking failing coil packs, considering it has random/multiple misfires in addition to the consistent misfires on cylinder 4 and 8. Just hoping to avoid doing that nasty job unless neccesary at this time. The weather has been quite poor, so being outside for several houra in thr snow and wind is less than appealing.

Thanks everyone!

 

Hi. You should post your technical questions in the Disco 2 section of this forum. You’ll get a lot more views there.

 

I did, once I saw it. The layout is a little different on my phone. If someone wants to delete this thread, that's fine, I'm not sure how to do it from my phone unfortunately.
