Hi Guys,

I have hit a brick wall with this. My D22 has the 3.3 fitted, done roughly about 300k and has developed a miss and lack of power at about 2800-3200 rpm.
Initial we thought injectors, so we replaced them. Then we suspected a leaking gasket under manifold so we had all that machined and replaced, still nothing.
Replaced the neutral position switch, still the same issue. We tried the TPS aswell but no luck.
The crank angle was replaced not long ago so i have rulled that out.
I even suspected plugs and leads still no luck.

Any help or ideas will be greatly appreciated.

Nik
