Misfire cylinder #6 : WTF?

**Hugo** · 08-12-2005, 10:29 AM

Why, oh why?

Got a check engine code yesterday, had it looked up this AM... msifire in cylinder #6. What causes that?

**byl** · 08-12-2005, 10:31 AM

faulty coil? broken sparkplug, faulty lead?

**Hugo** · 08-12-2005, 10:48 AM

It hasn't come back. coils are new (4 months old, plasma ones), so are plugs (iridium).

Pull the plug and check the gap

Tired of spending. beside, I'd have to remove your crappy HMS strut brace for that.

I don't have a feeler gauge. And I don't even know what the gap is supposed to be.

**byl** · 08-12-2005, 10:55 AM

then get a feeler gauge and compare 5 to 6?

Does your stepdaughter not know how to do that? delegate!

Perhaps. But I have the Haynes and I'm not sure that from one iridium brand to the other, the gap is the same.

I used to get cyl misfire: unknown cyl followed by misfire cyl 1, cyl 2, cyl 3, cyl 4.

Then I replaced my NGK's and it went away

**JoeZ** · 08-12-2005, 10:58 AM

But these days I can't get my idle right

**byl** · 08-12-2005, 11:12 AM

samer here, idling problems!

**JoeZ** · 08-12-2005, 11:31 AM

My idle is somewhat decent now (had some vacuum leaks after re-installing the dasc), but after about 800 miles stuff started going wrong.

I received CEL (Idle Speed Actuator - Open, and another Closed)

In neutral I can idle at 800rpms, touch throttle and revs jump to 2200...there is no middle ground

If I press the clutch at 1500 rpms or higher and let revs fall, it is as if computer doesn't know where to stop them. Sometimes I stall, sometimes it sputters and then jumps to it's regular 700-800rpm idle

Help

**Hugo** · 08-12-2005, 11:35 AM

My idle is silky smooth. Post whoring your way through the day, aren't you?

did you try another MAF?

**byl** · 08-12-2005, 11:44 AM

I don't know the 4 cylinder too much but ar you sur the intake pipe to the idle actuator is not leaking or not properly set up? I didn't pushed mine all the way in once and it didn't work properly

I'm actually very busy today....but i'm on top of my muli-tasking game.

nope, but i've replaced all clamps/hoses as well as

pressure regulator valve
idle control valve
throttle valve switch

Thing that really bugs me is how i kiss the throttle and it jumps to 2200, no way to control anything in between.

Throttle position sensor Joe?

Hugo call the ignition solutions guys and ask to speak w/ Ulf. He'll help you out.

You did, to the untrained eye. But I know you.
