Engine Codes are P1663, P1656 & P1315. Car doesnt pass 45mph. I believe it may be Camshaft Position Sensor. Replaced OCV already
If you suspect a clogged exhaust, check back pressure with a gauge. You can usually infer exhaust back pressure by looking at intake vacuum (easier to measure of course) which will be out of spec if exhaust is restricted. You...

I changed the throttle body on my Murano and ever since gas pedal is unresponsive? I did all 3 relearn procedures. What is wrong? 2004 Nissan Murano
