Rich as a bitch
 

I've just whipped out the sparkies and slapped in a new set, first time I've done the plugs on a WRX and I must say it was a breeze, everyone keeps saying its a pain in the arse?? You think thats a pain in the arse you want to try doing the plugs on a Straight six with half a tonne of air hoses and charge cooler on top :lol1:

I've inspected all of the old plugs, they are all equally dry and sooty as hell, we already had suspiscions it was running a bit rich (due to the dubious economy) so this proves it..

I'm going to fit a new ECU temp sensor as they tend to cause over fueling when they die, also there is a leak in the up pipe which will be sucking in air and not helping matters.

Now my question is is it possible to clean the MAF, the element looks a bit grimey, is it safe to spray it with carb cleaner?

And can anyone think of anything else that might be causing over fueling? Map sensor maybe?

Cheers :thumb:

lambda sensor..

you can clean the early phase 1 mafs with no problems and I think the phase 1.5 are okay with that too but a phase 2 is a no no.

Good call! And that little bugger is nice and easy to get to on the scoob :)

Its a 94' so I guess it should be ok to give it a quick squirt

Cheers.

Yep squirt away..

I assume newage cars are phase 2 then???

Why can't you clean them?

no newage cars are newage cars.. :) different again..

they are too sensitive.. you will fubar it!

Ok, sorry, by "phase" you meant the car, not the MAF, i thought the MAF had different "phases / models"....

Its all clear now!! lol

I believe the newage maf is similar to the phase 2 but I have little to do with the specifics on newage..

I wouldn't clean a newage maf either though..
