Default Rough Idle???

Ok, just drove 1300kms, first tank was 98 ron with an injector cleaner, the last tank was 98ron again, and now when i pull up at lights etc the car feels like it wants to stall. Bad fuel? Spark plugs shot? Any ideas would be good. The sparks have been in the car for 50000kms, but they are Denso Iridium 100000km plugs.

maybe have a look at the sparks... It could be bad fuel though. or if all else fails, take it to your mechanic. I'll have a look through my Haynes manual for ya to look for common probs though.

Could be the air filter as well, mine is black after 30k and needs replacing.

Not sure, but if your mixture is a bit rich, that might cause carbon deposits to form on your plugs.
(does that only happen to carby-equipped cars?)
(or do I just have my head up my ***?)

Cleaned filter and changed plugs. All is well now. Hopefully. Fingers crossed.

It seems to drive much much better now that it has some new plugs in it. The gap is suppose to be 1.3mm and i reckon the old ones i pulled out had spread themselves to over 2mm. I still have the factory wipers on my car after nearly three years and 81000kms. Still work like they were brand new.
