There is no H in Way, do you have a set of stock injectors you can put into the car, also have you checked for any boost leaks, sounds more or less a boost leak if your car is pretty much stock.

Whats the CEL for?

I'd also say its boost leaks or check the o2 sensor

 

[JEFFREYCASTGSX]

Your car runs that rich WOT, stock, with no modifications. What's are your AFR at idle?

10:1 is where many wideband controllers stop reading on the rich end.
From the factory you can see as rich as 9.3:1 at WOT but if you have aftermarket injectors you could be a lot richer than that if the car isn't tuned.

It seems that you have monkeyed with both the MAFT and SAFC but you don't know what the size of the are injectors your running. Not a good idea.

Find out what the CEL is for. Go look at the injectors and see what size they are. Take pictures if you can't tell. The factory injectors have the flow rate stamped in the side of the plastic part of their body below where the electrical connector is. Aftermarket will have some sort of identifying part number.

A "new" used car always requires a lot of investigation to figure out what hack jobs have been done and cheap ones even more so.

The DLC port is normally attached to the fuse box next your your left foot.
Instructions for reading the code are posted here and on the VFAQ site.

je n'ai pas mon Haynes avec moi, mais c'est la, cherce plus, pres du milieu. ta besion d'un voltmetre analogue, le port diagnostique est au dessous du dash au gauche du volant.

il tray to se if i can find it

and il use the multimeter if not il get a test light


there is no scaner that compatible whit these port right ??!!

There are dataloggers that support the Mitsubishi MUT protocol like MMCd, Pocketlogger, TMO.

It's so simple to read the error codes normally that I haven't looked for any scanners. An analog voltmeter, 12v LED, or Piezo Buzzer connected between pins 1 and 12 will let you count the output pulses for the codes.

i had the same problem on mine 98Tsi. i replaced the egr (make sure all of the lines are hooked up right also coming from the egr), O2 sensors, cat, and fuel regulator before it ran right. turns out it was the fuel regulator that was bad and i changed everything else for no reason haha if you pull codes on it it will more than likely read a fuel trim problem and my first check would b the regulator...
hope this helps
