Hi, I`ve had this problem for a while now and it`s now getting on my nerves. When I change gear the revs "hang" at what they where when I changed gear. The revs drop after about 2-3 seconds if you hold the clutch down. I`ve had this problem on the old engine as well, So I`ve checked for air leaks all ok, cleaned the idle control valve and fitted a new inlet manifold gasket.

Could it be down to the fact I`m running blue injectors and it`s over fueling ??

Any ideas ???
