cam not switching!

[Flamez]

I have just had my engine changed on my 318is H reg a G reg engine has been put in and it's not switching over from the small cam when revved it just limits itself around 3krpm. what can it be? i think he tried changing the camshaft sensor but its still the same. Please help its been a year since i have had my car and i really miss it ...

Can you explain what you mean by not swithing from small cam ?

[Flamez]

sorry what i mean is when i drive the car where it usually changes cams when revved up to around 3000rpm and starts pulling harder it justs starts choking and i have to change gear to keep the revs low, i cant rev up. i have to drive it in low revs on every gear. my mechanic thought it was the camshaft sensor but he changed it and it still has the same problem.

The way i understand it you have two cam shafts.
One for the inlet valves
and one for the exhaust valves
If your mechanic told you otherwise i would surgest finding another mechanic
As to the problem have you checked the distributor cap for wear ?

[Flamez]

sorry i just assumed that was how it worked. everything has been changed e.g. airflow meter. ignition pack. do you know anywhere i can take it. I live in hackney

anywhere apart from the original mechanic
