Rb Sounds Like A Subaru! Help!

[RB_GURL]

Hi,

About a week ago my RB20DE starting idling really bad and sounded like it was going to die at every set of lights. It sounds like a subaru when driving, a rotary when idling and shakes like hell!!!

At first I thought it was just air flow but now i think i've lost a cylinder or two. I don't think it is any of my coil packs either as I had a faulty one which I replaced a while back and all others were fine then and also cos sometimes it runs fine (when cold) for a while before it starts shaking and spluttering its ass off.

Has anyone had a similar problem and found an easy fix?

I am rebuilding a 20det for it at the moment so want to put all my money towards that instead of having to fix this one!!!

Thanks in advance!

Also thought I would mention as it has happened since this, but it probably not related. Sometimes when I turn the key to start it, everything dies and I have to adjust battery terminals to get it to start.

I had the same thing happen to my r32, it was just bad terminals posts. replace the terminals with some brass ones and then clean the posts with some battery post cleaner it worked for me

Sounds pretty much like a misfire on 1 or more of your cylinders. Isolate which ones are miss firing, swap coils/injectors from a known good cylinder see if it fixes it. Also do a compression test.

One of your cylinders is not sparking. When its idling, unplug each coil pack lead, one by one until you find the one which does NOT cause the engine to die even more.

Basically listen to how it sounds now, then find one which you can unplug which does not change the engine sounds, rpm, etc. Once you find that, you've narrowed the problem down to that coil pack, spark plug, part of the loom etc. I'd suspect either the spark plug it self or the coil pack is gone.

How do I know? First hand experience. I was driving normally then BAM, WRX time.

Thanks everyone! I unplugged each coil pack one by one and found that the last one which sits directly underneath the ignitor pack is the one thats causing me grief! Ran out of time to check exactly what the problem is tho so will have to wait until weekend for that. Will try swapping the coil packs around and will check the spark plugs.

Bloody subarus!!
