I am on my way to do a paperclip test but before that I just feel obligated to help those who are trying to help me by saying what I did check on the car. There is no oil in the spark plug holes (altho there are indicators that there used to be oil), spark plugs are new, mass air flow sensor has been carefully cleaned and air filter has been replaced.

Yeah, temperature gauge doesn't work so I did a little snooping with a mirror and a flashlight on the back of the engine and found out that there is a roung connector on top of the EGR valve, with a 3 tiny holes on it that just hangs around freely. I thought it should be plugged in somewhere but I couldn't find an appropriate place to plug it in...

Any thoughts?
thanks in advance

Can you show us a pic of the connector on top of the EGR valve?

Okay people, it has been a while but I am finally back with an update and I am asking for a bit of your time and wisdom.

I did manage to buy a used Siemens camshaft sensor (exactly the same as the old/broken one). I really thought it would cure all the hesitation and misfiring but to no avail! I just fitted a replacement sensor and the engine is acting the same as before. Low gas mileage, backfire and sluggish on the gas pedal. Performance seems to improve a bit while constantly pushing the throttle while driving, though. Paperclip test is still showing a camshaft error code.

Does the computer need some time to ''realise'' that it has just got a new sensor or is it something else?

Yes Rob, it is an original, made by Siemens. Or am I wrong?

Please people, I can not put into words how much I need your help.

With the new sensor the engine does rotate well past 4500 rpm but with the sensor disconnected it does not.
With the sensor connected, engine computer displays no orange light on the dashboard but the code is still stored as a camshaft sensor fault. The main problem is serious misfire between 1000 and 2000 rpm.
No oil in the plug wells and new leads and spark plugs have been fitted.
