hi just took car for mot its a 1997 ph1 200000+ miles it failed only on emmissions now this is what i have done given it a full service ie oil air filters oil change and fuel filter change i now have removed the anti tamper sheild from the back of the pump to show the max fuel screw which i marked and unwound 1 full turn took it back for retest still failed (what i did notice is that since undong the max fuel screw the throttle arm now moves abbout 1 inch before the revs move up before it was right from the throttle stop the revs go went up any ideas what i can do now to get the smoke reduced? also yes the garage was being good testing it ie done a fast test failed then they reved the car up very slowly to try to stop the amount of smoke still failed limit 2.5 failed 2.87 so not to bad i have realy got the car up to temp even booted it down the bypass (black smoke not the word lol) i am thinking worn injectors due to millage? but can i reduce it enough to pass the test these have no boost compensators etc on them although has a egr valve will dissconnecting this help? cheers guys need this sorted asap as mots out very soon.
