I just installed 8mm high preformance plug wires on my 89 325i and it gets better gas mileage and all that jazz, but now it seems that there's a bit of a miss fire when starting off from a green light.
it idles fine, runs fine once she's moving -- it's just in first gear from the "get-go" she sputters hardcore--there's sometimes a sputter in 2nd gear when I lay on the gas. It's also weird that she doesn't allways sputter but it's getting more and more frequent.
This problem didn't exist with my old wires...
I've had the new wires on for a while and have had this problem before but to fix it I just made sure the wire connectors were tight on the plug and that would fix the "sputtering" for a couple weeks. But now I've made sure all the connections are tight (to the best of my knowledge --- I mean how hard it to tell if a wire has a good contact with the plug or not???) but it still sputters......
please help I don't have the time or money to take her to a shop...
It could be your cap and rotor that are making the problems. Or the Spark plugs. I had the same miss/back firing on my m20 before i put in all brand new Bosch spark plugs, OEM wires, cap and rotor. Now its fine.
Where did you get the wires from? That sounds suspiciously like the problem I had with my new "8 mm High Performance" wires. I ended up using an old one (I love being a pack rat) to tide me over until I replace the engine.

I got them from bavarian auto. I called them and they will replace them for free but I just don't have time right now to wait for shipping...
I would put the old wires back on but ....uh....I cut one of the wires to get them off. The wire that goes and connects over by the air intake...I couldn't get it out so I got frustrated and cut of the end so it would just pull through....
so the old wires are gone....should I try a electrical tune up first (costing me a little dough) Or should I go for the free replacement on the plug wires?
I didn't go with the BMP wires, I went instead with the 8mm performance set from Ireland Engineering. Couldn't be happier with them. Easy install, look great, perform wonderfully, and cost about $30 less than the BMP ones.
Its all up to you man, I personally know that Irelend Engineering makes really good stuff. I also know that you won't be let down by BMPD wires. Its up to you, either way you go you will probably be happy.

so just to finish up this thread I want to say that Bavarian Auto 8mm plug wires are complete garbage.
First of all one of the connectors broke while I was installing them...took me hours to fix.
The day after I put the new wires on I began to notice a bit of a missfire/sputter. So to fix it I made sure all the wires had a good connection with the plugs and cap. This fixed it for a couple weeks then after that time I would run into the problem again, so I would tighten and temporarily fix the problem.
After about a month of using them the "sputtering" got worse and worse until I almost couldn't drive.
Tonight I replaced them with Ireland Engineering wires and I just got back from the "test drive" and she runs like the day she came off the lot 15 years ago (ok so I don't know that, but she no longer sputters...) On this test drive I tried everything from punching it in all 5 gears, reving the engine hard, and flying up a hill with a 26% grade....and not one sputter. So as far as I can tell right now the problem is fixed and it's confirmed that Bavarian auto wires are no good...at least the set that I got.
Not to mention she feels a little "zippier" with the Ireland Engineering wires....
So did you get the Ireland 7mm's or 8mm's? They don't mention if their 8mm's are well shielded to prevent interference with radio and other electronics. They are a good price compared with other companies 8mm wires, so I think I want to pick them up, but I would like to hear your opinion first!

I got the 8mm's and so far I haven't noticed any interference at all. But then I don't listen to the radio....only CD's. Would it have the same interference?
they are better in every way then the Bav auto wires......well I liked the bright red color of the bav auto---Irelands are a deep blue.
I've only had them on a couple days now and my car runs geat....a very good purchase that I would definently recomend.
I'll keep on driving and let you know if I have any problems with them...
(over the past month I've spent over $300 on plug wires (bav auto combined with Ireland)......I told that to my old tractor mechanic grandpa and he almost fell over dead.....he's never spent more then $20 on plug wires.....these BMW's are pricey little things....)
