Hi i have a 1996 Nissan 200sx SE-R with about 150k on it, the car has never given me any engine trouble until now. The car trouble started out as overheating, which i quickly discovered to be the thermostat. It ran fine for about a day, then it started throwing 4 differnt codes, one was a coolant temp. sensor, tested it was bad so i replaced it, the second was a knock sensor, tested it it was just loose, 3rd is a maf sensor/circuit, checked it everything was fine, 4th is the IACV/AAC valve. The engine also surges when holding the accelerator steady. I checked the EAG valve and t seemed to be working fine, car smells like its running very lean, which makes me think its either a fuel delivery problem, or a vacuum leak. or possibly both. Anyone have any input for me cause im at a complete loss. Thank you.

Could be clutch cable adjustment needed. Could be bad clutch cable bad or linkages to. If noisy bad throughout bearing. How many miles on clutch? could be worn out and need to be changed.
You have solved your own problem. I have replace many of these units. It is much simpler to carry and extra key than to screw arround with the old lock assembly. Keys and tumblers ware out like everything else. Let me know if I can help[
Sounds to me like you have a leak somewhere in the intake system. The idle fluctuation sounds like a vacuum leak- and of course, when the turbo spools up, you have positive pressure replacing vacuum. Look for a loose hose clamp or a torn hose, etc. etc. By the sounds of it, you shouldn't have any trouble finding the leak.
