Follow up on my previously posted
problem with a rough bumpy idle
which eluded the auto mechanic
and diagnostic equipment.
The 'camshaft adjuster magnet'
was replaced (located at front of engine).
It no longer bumps and surges
on one cylinder while idling
(although there is slight sublime
turbulence persisting in idle.
I added injector cleaner to tank
and hopefully that will diminish or
end that.

Where is the camshaft located exactly? What is it? HOw much did it cost you? I have same problem, occasional rough idle. Thanks for the info.

How (or who) did you find the solution to your problem?

The part that was replaced was the camshaft adjuster, I feel sure.

I have seen where they can stick at times. When this happens, it leaves the intake cam in a slightly advanced position. To replace is a Pro-only job.
