For the 150BHP 16V engine the Fiat Part Number for the EGR restrictor plate is 55225287. This number may have been superseded but your local Fiat dealer parts department will/should spot this and use the later part number.

Avoid part number 71751468 as this part is much more expensive and does not have the integral rubber/silicon seals.

I have to disagree slightly, Fiat quote a torque for the fuel filter ring of 3.0 daNm.

You can't set 3.0 daNm by hand.

Well it is slightly marginal I think.

3.0 daNm is 22 foot-pounds to be applied to a ribbed near 6 inch diameter ring nut.

I accept this is very two hand tight but in all the fuel filter changes I did I never had a leak and found the ring nut still often a challenge to remove again at the next service. Would add that we are talking about a two arm twist as opposed to a typical screwdriver wrist twist action.

I think the big isssue with the fuel filter housing is people using strap wrenches or "pump pliers" on them. They distort the ring stopping the torque being appied properly, The proper tool applies torque at 3 poins 120 degrees apart witout clamping or distorting it.

Hand tightning is better than the wrong tool.

Changed the Mass Air Sensor and it seems to have worked. Got more response when accelerating, not brilliant but don't suppose performance has ever been fantastic with the Croma

The 16V is certainly nippy enough. It would be worth resetting the learnt parameters with Multiecuscan. The ECU may have learnt some bad habits compensating for the faulty MAP sensor.

Very valid point to make. Fiat had issues with learnt parameters a few years ago where new cars with cold engines had the nuts revved of them during the transported loading phase. ECU learnt that normal starting and drive cycle procedure/parameters are cold engine, start, full power high revs followed by engine off. (in the early days of adaptive ECUs)
