Rough idling, no loss of power
Hello all, a few weeks ago my ML350 loss power and would go 0-60 in 10mins (ok slight exaggeration).. But it was definately slow.
Next morning on the way to work, same deal, so after work decided to take it to the dealer. However, it ran fine and when I got to the dealer, he just suspected bad fuel.
A week or so later after 20 mins of driving, it suddenly had a rough idle but didn't lose power.
In between that time I put in petrol from a different petrol station. (Surely I can't be that unlucky to get bad fuel again)
On idle, it would go up a few hundred revs for a few seconds and down for a few seconds repeatedly.
Regardless whether it's cold or warmed up it's the same problem.
Could it be my spark plugs?
Anyone else have any suggestions?
