hey guys just trying to mot the zed but itsd running rich a ballsing up my emissions how do i adjust the mixture a tad to get it back down ? is there a mixture screw on thrittle bodies? heeeeeelp

Could always add Injector Cleaner stuff sometimes helps or (and i hate to say this)

 

Go for a Razz so your cats are really HOT then wack it straight on the Emissions and will knock them down a fair bit!!! As for A/F mixture i cant help you there!!

sounds as if your o2 sensors are bust that causes it to run very rich :(

Wouldn't adjusting the fuel pressure help??

Or the ecu engine temp sensor is faulty / bad connection.

You cant adjust fuel pressure on stock regulator.

Try Cataclean mate:) Its awesome stuff that really works, my mate put some in his car after the mot tester told him to try it and hey presto! it past the mot! its in a silver bottle & costs around £15.

Good luck :)

You need to get a conzult on it to see what the problem is.

 

You could also try try resetting your ECU.

 

Apart from chip mapping and adjustable FPR's there's not much else you an do to get it to run leaner. Nothing I would advise without diagnosing the problem first anyway.

 

Your fuel pressure if you wanted to check it should be running between 42 - 45 psi.

Think you need a new spell checker too. :wack:

 

Trick to reduce emissions at idle for MOT test is to pull off the little boost hose that sits on the left hand side of the balance bar. Your emissions readings will drop right back. :D

But remember to plug it back in after the MOT or it will run like a shed.
