01 disco P1300, P0303, P0302, P301
I did a tune on my disco, new parts are wires(denso 7mm) ngk g-power platinum plugs, standard motor products coils.
plugs are gapped to.040
it has a rough idel, cuts off when turning sharp to park.
runs fine when moving down the road
getting the codes :P1300, P0303, P0302, P301
running 2 cans of seaform in a full tank.
i have cleared codes 4 times, allways these.
i checked the plugs, dry no oil on them
VERY new to working on discos. not sure what else i need to check. not want to take to a shop and get slammed on a repair bill

How about the coil packs? Were you able to visually inspect it when you replaced the wires? Was there any corrosion? How many miles do you have on your truck?

Ignition replaced and new. Assuming, all plugs are inserted correctly. (Both side of engine misfire) Gas, full tank with 2 seafoam. While troubleshooting your problem, I would suggest to get the premium gas at the same exact station always while straightening the problem. A bit too much on the seafoam side. No seafood next time just add more premium gas. We are not waiting for another code at this point. Sometimes, old rovers will adjust in this event until a new code shows up. reset again. At this point I'm again assuming that your SES light is not blinking still. 70 miles is far enough, unless seafood is causing the misfire so add premium gas for the meantime. Also, recheck the plugs if they are seated properly. I usually count the turns when replacing plugs coz sometimes they are halfway in and seems tight.

Well, with regards to seafoam, I'm sure its a great product but I guess you have to use it in moderation. It might end up cleaning its path but a larger gunk can get stuck in the injector for a while. Just a guess. I did exactly what you just did thinking it was good but my truck won't even go over a bridge after tune up.
About gapping, a fine tuned equipment need precision and also the proper gapping to maximize its performance. I just install my plugs straight from the box, I don't gap them. Here, its up to you. Cheers!

You can always gap them yourself. As for seafoam, it has its uses but I prefer royal purple. When I did my head gasket job, I had my injectors done by a guy in New England. Cheapest around n I alway use premium from new gas stations(newer tanks) but had one injector with 3 out of the 4 holes blocked and one with 2 holes blocked. I can tell the difference.
