My service engine light came on and I used my evo scan program to check the code, well it said the I have a injector circuit and EGR problem so I removed the EGR and clean iit up to see if it will fix the problem. But after doing that I check for the code and I got more codes this time Injector pulse, fuel pump relay, speed sensor, parametric sensor, knock sensor and every time I scan the Ecu I got different codes! I have chech to make sure I dint un plug something but everything looks fine, there is anyone up there the may have a problem like that or know some one who did? I talk to a cuple of my friend and one suggested a bad Ecu but the car runs fine and the service light is off, and my other friend things it maybe a ground related problem, i have to mention the my battery was relocated to the back in the trunk, so I got one ground from the intake manful to the fire wall another from the battery to the trunk and one more from the inside the fender next to the fuise box to the starter so I don't know if this have anything to do whit this problem, but this problem star affter I tuck the EGR off to clean it up any help I be great.

Thanks..
