classic running issues HELP

[tatty]

Right this is a follow on from my previous post....

Car has a clean ECU (no fault codes)

but when driving under a slight throttle load the car feels as if the brakes are being applied on and off.

The boost gauge rises and falls as this happens,

I have checked for leaks and replaced all the vac hoses but still the same.

Has an HKS mushroom filter but don't think this will affect the running.

Also it boost upto .5 bar and no more, i did think it should of been higher than that.

So 7 minutes previous to this thread it was running fine but now it's not?

The symptoms you are providing sound like you've got a knackered MAF sensor or circuit.

Aftermarket filters, especially the oiled ones are known to ruin the sensors. The version 5/6 (yours is a 6) are particularly susceptible to this. It maybe worth finding a local known working one and fitting it to your car to rule it out?

Car does run fine i'm just being fussy.

Maf is good as no fault codes at all.

Did hear that they don't like filters so am looking for a standard airbox as i reply.

Yeh trying to find a MAF just to try to see if it changes anything.

Might just have to go to AWD in Perth at the weekend for a check.

Cheers for the reply though

I could meet you at broxden tomorrow lunchtime? Am heading back from Newcastle in the morning, I have the box but no filter so you will need to get a hold of a panel filter.

You up to much this weekend Dave? Am hitting newcastle at stupid o'clock tomorrow for a new wing then back down the road again for ingliston with Aberdeen Scoobies on Sunday.

[WUZ]

Lewis - you should have said the wing was in Newcastle as Ali and I left there yesterday afternoon on the ferry to Holland for our Ring Trip.

[lewisscoob]

Ah no worries Russell, I enjoy driving. Also, I did think about you and Ali this morning but didnt want to disturb or wey lay your trip.

Brian also offered to carry it back after his stagger down there next weekend I but didnt want him looking like a tool with a second hand subaru front wing under his arm
