from memory on earlier posts, you don't have a VVC, do you ?

There's no MAP sensor at the 120bhp engine :)

In a 97 F, the map sensor is in the ecu unit at the back LHS on the engine comparment/boot wall

thanks dieter yep i dont have a vvc my car its 2001 1.8 k sorry just concerned as sometimes i get a judder stutter, when driving not all the time .. darren

If it is 2001 it will be EU3, these engines have a combined MAP and IAT sensor on the top of the inlet plenum.

I have a few spares here if yours is b*ggered and i am just up the road from you.

As mentioned by Dave, it's located on the top of the inlet plenum.

You need to remove the engine cover (11 bolts) to get there.

On the other hand there could be also an intermittant problem with any other sensor, or the connector to the ECU.
The ECT Sensor (Engine Coolant) gets in my mind.

I'm sorry not much help.

If Dave Andrews can't diagnose and fix it(12th Feb post offering assistance) - then nobody can.
