When did you last service the vehicle. before going for engine filters, fuel pipes are okay I guess in a very hot humid country like sri lanka filters can go off quickly. How long has this been struggling first.

The MAF has little effect on the running of the engine on an L Series, it is only used to control the EGR I believe. If it is not smoking when hesitating I don't think it will be the EGR.

The MAP sensor is used to know air flow for fuelling.

It could be the timing of the fuel pump, but if that is out, the car will usually be very difficult to start. The wiring from injector 1 is also used for timing I believe, so you could check that - plus wiring to the pump.

Never touched mine, but presume its on the inlet manifold/plenum so that it knows what pressure the air going into the engine is under.

The Rave Workshop Manual will have details about it. There's info on downloading it here...

You're after the Rave03 which is for the L Series.
