Running on two cylinders?


To view links or images in this forum your post count must be 5 or greater. You currently have 0 posts.

Been trying to figure out why my 2006 R6 has been running so sluggish. It has a really rough idle and throttle response is delayed. It was fine up until I was in diag mode testing out my injectors and coils and I heard a something pop like a can of soda opening. I moved my ignition coils around put new spark plugs thinking that was the issue, but no luck.I even moved my injectors around and its the same cylinders that aren't firing. Any insight would be great.

Re: Running on two cylinders?

The pop was probably an ignition in the cylinder. Whether or not that could blow a gasket, dunno. I'd think there'd be warnings in the manual if that were a potential though.

What you'll want to do is enter diagnostic mode and manually fire spark on each cylinder; with the plugs out. If that pans out, then run a compression test.

So you put in new spark plugs, and since that didn't solve the problem then I would replace all 4 coils and see if that fixes anything.

He mentioned that he rotated the coils and the same two cylinders aren't heating up the exhaust pipes.

Re: Running on two cylinders?

Yeah, I even removed the coils out from the cylinder with the spark plugs and fired them outside without any issues. I ordered a compressor tester today and see if maybe somehow my exhuast valve is shot, even though it has had a valve adjustment 3000 miles ago.

Tensioner look good; timing still set?

During the valve adjustment, the timing was set then. Not sure if it could have gone bad in 3000 miles, but I'll double check

Re: Running on two cylinders?

if you moved the injectors and confirmed you have spark this means you have wiring or ecu issues to two of the injectors.
do you have a power commander or something like it? if yes, remove it and test again

No PC installed, I was afraid it might be the ecu.. Will test the compression first and see if they are within spec.

Re: Running on two cylinders?

they would still heat up the exhaust pipe. you're not getting fuel to those 2 cyl if you confirmed you do get spark.
