Not unless they are blocked...

Also, how did you clean the MAF? They are quite fragile.

Have a reread of Scouse's comment, I think he was referring to a "dynamic" fuel pressure measurement...i.e. connecting a pressure gauge to the fuel rail then driving the vehicle for a distance to see what pressures were obtained when it lost power....a static test doesn't tell the whole story. There's no hint that the mechanic did a 'dynamic 'test

Cleaning the Maf is not the issue here, The Maf can go faulty and give intermittent bad running and stalling hence my suggestion to try a known good one.

If anyone wants to clean the Maf it is simple if you have the right tamper proof bit to remove it. ( once off refit with normal screws for next time )



Remove the two screws holding the insert into the Maf housing. Remove the insert and electrical connector. Spray Maf Cleaner or contact cleaner into the "air Flow" orifice onto the inner wires. Repeat a couple of times. Done

Cleaned it with a spray, I'll check with my mechanic but he told me he tested the fuel pressure while driving. Cheers.

Did you put another/new cps into it?

Hi mate, no not yet. Would like to try and be and sure as I can it needs replacing before I buy a new one. Cheers.

......or even an air leak somewhere along the air intake since you are complaining that you lose power on acceleration.

Getting de-ja-vu again!

Was under the bonnet this morning and noticed that both screw heads holding the throttle position sensor are broken off. The sensor seems to be still attached fairly tight, although giving it a jiggle the engine seems to rev higher. Could this be the cause of my problems? Cheers.
