My car hasn\'t got an mot at the moment so starting the car up every other day (mot next saturday).
couple of days ago it was completely fine and ran no problem. however just now I started her up and black smoke came out the exhaust (running rich due to how strong petrol smell was) until she warmed to optimum temperature then disappeared (baring in mind as you well know it isn\'t cold at the mo lol) , but at the same time was idling at approx 1000rpm revved the car then jumped up to 1400rpm, when revved again, then went down to 1k for a second when i realesed accelerator then straight back to 1.4k and popping every now and then through out the whole time engine was running.
any ideas guys???
going to get my oil changed along with mot as well as oil filter change and fuel filter if there not to difficult to change and a full service by a specialist.
thanks in advance,
