Question about 1998 Nissan 200SX
When i start my car idle goes up too 1500 rpm then drops too 1200 rpm and stay but i put it in gear any gear idle goes up at 1500 new maf., tps. sprk.plgs.air+gas filters
IAC valve problem. Nissan has a updated harness (with one way diode inside of the harness) to prevent backfeeding for the IAC valve and a new IAC valve also gets installed. That's where I would look. IAC valve or "idle air control" valve.
