Can someone point me in the right direction as to what could be causing this problem ?

I start the car up and the revs drop and the car cuts out.

If I start it and keep my foot on the accelerator the car will drive ok, but as soon as I take my foot off the gas it cuts out.

Thanks in advance

 

Time for a new MAF I think.

 

knew someone would say that ;-)

tried a new maf, not that

also had a new 02 sensor fitted, 4 new coilpacks, 4 sparkplugs

 

Have you cleaned the idle stepper motor?

whats that ?

forgot to add the car is a 93 wrx

ta

 

Normally a cream/grey coloured valve with 3 wires, bolted to the inlet manifold, next to the throtle body passenger side.

The moving coil part of this valve can get stuck.
