Hi guys, quick one. After my recent injector change (delphi re-furbs) i now have a slight 'tap' at around 2k ish revs. We did loose one new copper gasket from cylinder 1 when changing which caused ever such a slight leak, and used one of the better old ones. I thought this may have caused the problem, but have changed that for a new one now and the noise is still there - even when warm. The engine runs so much better since the injector change, and all the previous rough running and other annoyances have gone, but it has a tap, and feels ever so slightly under powered now. We successfully coded the re-con injectors, so i doubt this is the issue. Starts on the button and has perfect tick over and drives really nicely. Just slightly annoyed at the tap and slight lack of power. Any ideas peeps??
Cheers,
K
