Hello Everyone,

My story goes like this :
My car started running poorly, rough idle, misfiring and check engine light. Long story short: Its gone through 3 mechanics and 1 Nissan dealer and my car still runs like crap. I am lucky if I get 210 miles per tank. The code stored in the ECU is 32 - EGR valve. I've replaced the egr valve twice already and the darn check engine light still lights up. I've replaced the following: spark plugs, wires, o2 sensor, air flow meter, catalytic converter, distributor cap and egr valve. The dealer told me that my injectors were clogged so they went ahead and took them out and cleaned them - They took $350. When the check engine light came on they told me that it was the EGR Valve and that it would cost me $650 to replace. After hearing that I RAN!!
I've replaced the EGR Valve but that has not changed anything. The car has a rough idle and it slightly vibrates on drive and to top it all off the check engine light is on.

Any help will be GREATLY APPRECIATED!!!

P.S. I've reset the ECU but the check engine light come on after 20 or 30 minutes of driving it.

THANKS
