Running too rich, Running too rich/Co to high for MOT/Exhaust Black Options

[yosemitesam]

Hi guys,
Running a 95 import 2litre gen6 ST202 SSII
I have a major overfuelling issue, using way too much petrol, the Co's are way too high and the exhaust pipe is black.
Any suggestions will be gratefully received.
Ive read on forums about resetting ECU but how do you do it? They suggest taking out certain fuses but which ones?
Got MOT soon and need to get it sorted.
Wil even try new/2nd hand lambda probe/throttle body/air flow and Co meter if itll help.
Hoping someone might have a quick fix as money is tight.
Thanks in advance
Sam

it says in the information part of the sight how to reset the ecu.. and are you sure its running rich or are you just guessing. my ehaust gets black over time. and if its running rich it should be a wet blackness to the tail pipe. and your plugs will most likely be fouled. and another way to hint that your running rich is go out on the road and do some pulls from low rpm to higher rpm. if alot of blackish smoke comes out that might also be a sign of a rich engine.

Here's how to reset your ECU. First, start your car and let it warm up. When it's reached it normal operating temperature, turn the car off. Then, pop the hood and remove the relay fuse box cover and remove the following fuses: the Hazard fuse, the EFI fuse, and the ECU fuse. Take them out and leave them sit out for 1 minute. Then when the minute is up, put the fuses back in and start up your car. At this time the ECU is being reset so you can take advantage of your mods and get better gas mileage. When you start it up, let it run for exactly 10 minutes, then turn your car off. then start it again and you wil notice your car idle better and from that point on you will now have better gas mileage and your mods will be put to use.
