strange smell and rev issues

[carribine]

My 08 plate 1.8 TDCI Ford S Max is acting strange, when the revs reach about 3500 rpm the engine won't rev any higher and the car 'stutters' like when hitting the rev limiter, also i think there was quite alot of smoke coming out of the back (not sure it was dark).

When i got home and got out of the car there was a strong smell from under the bonnet on the passenger side. The smell smelt either like rubber i.e. a belt or oil.

Has anybody experienced some thing similar?

Cheers

Might be a blocked cat. Or a broken/dirty Mass Air Flow sensor.

My money is on either one of those.

Any warning lights on the dash? It could have gone into limp mode.

Edit: Is it similar to this? http://www.fordownersclub.com/forums/topic/15795-f...

Another vote for blocked cat.

Having read that link that was kindly posted, I'll also add this:

"Took it back to the Ford main dealer for the day and they printed out some circuit diagrams. They tested the mass air flow sensor (MAF) and throttle position sensor and both were ok. They tested the wiring and found an incorrect voltage at pin 3 of the MAF. They traced this back to pin 14 on the battery junction box, where they found a bad connection. They "repaired and made good the connector". Charged me 94 quid and washed my car a second time in a week.
Gave the car thrash around and seems ok."

Result.

And not too expensive.
