Question about 1997 Nissan Pickup

2 Answers

1997 Nissan Pick up 4x4, 4cylinder

After my truck warms up and runs a while it stumbles at cruising speed and it will also cut off when letting off of the accelerator. The codes that have come up on mine at first was code PO510 and also code PO440 and 446. I replaced the closed throttle positioning sensor I still have the problem. And only one time the PO110 code came up which is the intake air temp. sensor. I'm still having the same problem what should I do?

2011. Why has cruise control failed?


cruise controls are controlled by several units
VSS or road speed sensor, clutch and brake sensors , engine speed (tacho) and the on/off switch
cruise controls will disengage automatically if the road speed is too slow ( higher for manuals than autos ) so if the road speed is below around 20mph it may not engage at all as the VSS says it is too slow for the engine rpms
check all sensors for adjustment

1986 Ford f250 stumbles


You would need to figure out if the problem is too much air or not enough fuel.
The carb has three internal circuits - - idle, cruise, and accelerate.
Fuel flows thru each circuit from the bowl to the venturi.
You could have a vac leak that is allowing too much air to enter the intake, or the idle circuit on the carb may not be adjusted correctly after the engine warms up.
Or it could be something else.

1986 Nissan King Cab pick up. Runs good when giving gas, but cuts off at an idol. Have replaced Altenator.


Based on the information provided, it sounds like a bad TPS (Throttle Position Sensor). The TPS controls your idling speed under all conditions. When a TPS goes bad, you will usually notice the vehicle will idle when the engine is cold but once warm or with the AC on, it will sputter or stall.

Stumbles while cruising or in light pull--dies at idle. Runs good at RPM above 2,500.


I AM LOOKING AT IDLE SPEED TOO LOW OR EGR VALVE LEAKING STICKING OPEN.
