Poll: Do you have a rough idle/misfire with your 335i?

S4to335 · 12-05-2008, 12:23 PM

Just curious on how widespread this issue really is.

Mr. 5 · 12-05-2008, 12:30 PM

I did but I found that it was my clogged PCV.
I know you saw my thread, but did you check your PCV to see?

RedGT3 · 12-05-2008, 12:30 PM

Yes but was fixed by replacing #2 sparkplug, and #2 injector. GL.

Been running fine for a little over 20k miles, never had to get anything replaced

Mine was running fine up until 26,000 miles, then i started experiencing weak starts (revs only hitting 5-600 instead of the nice 1500rmp). Then one day I got the reduced engine power message, but never recieved any long cranks. They replaced Injector #1 yesterday, we'll see how it goes now.

When your car misfires, what are the tell tale signs(aside from what the C-Reader says)?

Because I THINK my car misfires sometimes during idle on cold starts. It basically has very slight hiccups if you will, when idling down to 600 rpm.......Is that a sign of needing to replace spark plugs or failing HPFP?

Didn't mean to thread jack.

Thanks

5soko · 12-05-2008, 03:01 PM

Running smooth. 15k+ miles.

BMW_TT · 12-05-2008, 03:14 PM

23k and still going

joec500 · 12-05-2008, 03:19 PM

Only at Idle and only when I first start the car after it's been sitting for 1+ days

Problem solved 2 days ago during service by replacing the whole six spark plugs

I almost hate to vote in polls like this for fear of jinxing my car. Oh well too late for that LOL!!!!

2e9x's · 12-06-2008, 09:47 AM

Interesting...so I read this thread and about 10 minutes later my mom calls me and she is having a really rough idle with CEL and limp mode. The car had been sitting for a week. After shutting the car off a few times and re-starting it, the car ran fine.

S4to335 · 12-06-2008, 10:32 AM

What the heck are you having your mom drive the car for?

OpenFlash · 12-06-2008, 01:11 PM

Had a rough idle and a persistent P0302 code about 15k miles ago. Fixed by replacing spark plugs.

AJ@ECSMotorsports · 12-06-2008, 02:48 PM

So seems like spark plugs from BMW are bad or the gap needs to be shortened for better spark..?

Nothing is really bad about them. But yes, a smaller gap would be beneficial. None are available just yet though.

S4to335 · 12-06-2008, 03:36 PM

They only replaced one after inspecting them all ...I will HIGHLY recommend they do them all this next time. I just wish I could get re-chipped before the Laguna track event this monday. Ugh. Not gonna happen.
