I have no faults on vag com, timing is spot on and the engine doesn't leak or burn any oil. All is well appart from a couple of minor niggles. When the engine is warm it still seems a little bit noisy and it also seems to have a stutter when you blip the throttle lightly on the wind down which also happens when driving causing a shudder at certain revs. It pulls well but there isn't a lot of torque compared with the old IDI engine it replaced (considerably less) and the economy is no better either.
Anyone got any ideas? Everything pipework wise is new on the N75 and the wiring is fine but they are just minor enough to be annoying. I also find it has occasional lack of power (not limp mode as full boost is allowed) Could this be a problem with the N75 valve which is a bit noisy and worn. I also have very high readings compared with specified on the MAF at idle but it reaches the required levels under load easilly.
I have a list of things to do in the future which might be causing the problems. Worth doing (see list below)?
Decoke head and grind the valve seats.
Replace camshaft and lifters.
Remap.
K&N panel filter.
