Hi, can any one help me on my Ef. It only runs rough when I start to accelerate for a second or two then is fine all the way up the revs. Noticed it only does it in the low revs around 1000-2000rpm. It's was playing up bad a month ago and found one of the leads was stuffed.Had all the leads changed and it ran like a dream for a month then this is happing now. Spark plugs were in good shape when I changed leads. Not sure if it's fuel or spark problem. Anyone had the same problem?

Yes, I replaced the leads and coil pack... problem solved.

Found the problem, the inlet manifold gasket was split on number 6 cylinder which was causing the car to run too lean. Thanks anyway bro.
