sounds like the maff is fooked, but if car is dying when unplugged can't be too bad.

have you had a comp hooked up to it to see if its saying anything else?

new maf should the hesitation out- common codes on the model... Keep us informed

Also see some other threads example:

Normally coild down to sensors.

Gareth

Personally would leave buying the maf till last and would replace whats coming up as fault codes first-when my maf were fooked car wouldnt tick over though didnt drive too bad replaced maf all gd but still had slight hesitation so bought new plugs dropped them in (gapped to 1mm)-the same ran it like this about a month then saw a thread on sn somewhere about plug gaps and the fact that occasionally its possible that on full-ish boost its possible to blow the spark out now generally this were applying to heavily modded scoobys running much higher boost............................................. ...however thought well it aint gonna cost me owt to try it plugs are ngk pfr6b`s. Now on here http://www.sidc.co.uk/faq.htm#2.1 it says gap 1-1.1 mm-mine runs between 14 and 16psi but were almost getting like a missfire it were that bad,so anyway dropped plug gap down to 0.7mm and hey presto what hesitation car runs mint couldnt believe it.

so personally would replace problem sensors that cel`s flashing up,do a ecu reset then see what happens.(My cel did flash 23 up tho when my maf were knackered however know this isnt always the case.)If no fault codes after maybe change the plugs,this is all trial an error though, scoobys are tempremental when they wanna be.
