Question about 1995 Nissan Pickup

Open Question

1988 Nissan Truck 4 cyl 2WD - Extremely high idle speed (4k rpm plus) in cold weather. After engine warms up idle drops to about 2500 rpm. The problem isn't nearly as bad in hot weather - will idle down to around 1500 rpm. An air-conditioning mechanic said it needs a new cold idle solenoid. Parts people I've talked to either don't know what that is or say it's no longer available. Anyone know how to fix this idle problem?

SOURCE: idle too high +goes higher when put in gear (manual transmision

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.

SOURCE: High Idle

I have a 2001 Nissan Altima and mine did the same thing. We replaced the intake gasket. It costs around $5.50, but it requires several different kinds of tools. We spent over $100 in special sockets, etc. But once you replace that gasket, it will idle better.

Idle problem integra


check the MAP sensor (manifold absolute pressure). The ECM (car computer) uses that to keep idle at minimum 750 RPM. It's normal for it to run high when cold. These small 4 banger motors typically run hot, and they won't run right IF they're NOT running hot, ergo the idle is usually high when it is cold so as to cause it to warm up quicker. If the RPM's drop below 750, suspect the MAP sensor, &/or ECM.

What should my 2010 camry rpms be at in park starting the car


Hi Joseph, When starting the vehicle from cold in cold weather, the RPM can be as high as 1300 and in temperate climates about 1100 RPM. The RPM will drop to normal as the coolant is warmed. Normal idle speed is between 750 for Auto and 650 to 700 for manual transmission. Regards John
