Test the Temp Sensor. I have a 240sx and apparently these things are notorious for burning out. I am in the midst of replacing them so i can smog. Best idea is to get one at a pick and pull (make sure its good) and throw it on there. Otherwise you will be spending 110 bucks on a brand new one as opposed to 35 which i just got mine for. You may have carbon deposits in your EGR system, but that is common. Too much WILL effect your cars EGR function. You can check for blockage but sticking (try not to laugh) a rubber tube the bottom hose of the EGR and sucking whilst the engine runs. If it starts idling rough or dies, then your system is still clear enough for it to be functioning properly. Realize that this system works off of exhaust fumes, and IS prone to carbon deposits. I paid 170 bucks for a mechanic to tell me i needed to replace some stuff. Otherwise he would graciously only charge me 770 bucks to do it himself.
