Hi ive got a s2 an its misfiring , an when u go 2 drive it its got no power u can av ur foot 2 the floor an it will take ages for the revs 2 go up ? ANY HELP WUD BE GREAT

 

Need more info really mate.

Is it misfireing all the time.? I Start with compressoin test and check the obvious along the way. ie plugs, leads Ect.

 

it misfires just when u have it running , then u have 2 hold the revs up otherwise it cuts out . then when u go 2 pull away it hasnt got no go ? ive just changed the metering unit that helped a bit but its smoking a little but its black ?

 

over fueling if black smoke, could be a result of the misfire

 

i had this problem not long ago m8, it was yellow sensor under the inlet, had my car running exactly like that and took me 3 month to find out, lol, it cost me £17 to replace, and as soon as i changed it the car ran like new again,
