hey guys, my cel was on for a while and i didnt have money to check it out. anyway, luckily my friend had the handheld tool and it took me awhile to find the port (behind the ashtry for those looking for it). anyway it said that the egr valve has insufficient airflow. i hear cleaning this out helps most of the time. problem is i dont know where it is and how to clean it. somewhere around the throttle body or intake manifold and thats it. dont even know what it looks like so pics well help. also if i do clean it and it doesnt work, how much is it to replace? another thing, my turn signals just complete died out of no where. all other lights work and i tried checking the fuses and theyre fine. what else could it be? there is an alarm system with the stock deck. thanks a bunch.
