My brother has a 2001 Nissan Xterra with a 3.3L V6, 200k miles, 2wd that is causing me a bit of a trouble. Allow me to explain.
It all started over a week ago when I replaced the driver’s side motor mount. After I replaced the mount, I started Helena (name of the Xterra) and was immediately confronted with a very high idle (4000+ RPM). I have 3 error codes, 1 of which is pending: P0325 (knock sensor-PENDING), P0505 (MAF Sensor Malfunction), P0100 (Idle Air System Malfunction)
This is what I have checked so far:
1. MAF sensor (cleaned the old one + put it back on; put a new one on). Did disconnect it to see what would happen, and the car idled from 1000-2000 initially. I then turned it off and put the connector back on the MAF.
2. Idle air control valve (pulled the intake off, tested resistance between the terminals and cleaned the IAC, put new gasket and hoses on the intake and put the intake back on; hooked up a new IAC to it, gave same response as old one)
4. Throttle and cruise control cable
5. Connections (pigtails, etc) within reason (didn’t go all the way down the line to the computer)
Please, for the love of God, help me. This has consumed a FULL week and I really need to start working on my other cars.
Edit to add: Car does not have a throttle opener, just the accelerator pedal and cruise control cables.
