Dutch: You will need a tuner that has experience in changing hex settings in Ecuflash. You can find this fix on www.evolutionm.net and search for "CEL fix". Also try this site: www.aktivematrix.com

ExecutionIX: This car has been flashed (far as I know, don't know who or what did it) But since it has been flashed should the check engine sign disapeare?

That cel can be fixed easily by tuning. There is a hex change in Ecuflash that can fool the ECU to see the 02 difference as normal and not throw a cel anymore.

yes it said to u that the probe Lambda isnt working thats because of the exaust wich doesnt seem pretty much stock

the CEL is prolly on due to having no cat. very common

Haha, yeah it was. Nothing like trying to push a car that has its check engine light on.

is that the check engine light???
