Question about Cars & Trucks

1 Answer

Where is the ICV located on a 1994 Nissan Quest? I know it's somewhere near the throttle body but I don't even know where to begin. Recently, ther was a viscious snowstorm, and I had to work so I drove. Afterwards, I began to notice my car idling erractically. Could the liquid salt be the problem? The soot that comes from tires and snow mix, I just don't know, Im totally clueless about this. A mechanic said he couldn't diagnose what it is.

SOURCE: PCV valve? IAC valve? Sparkplug wire? Throttle body? Vacuum hose?

the most common causes are plug wire, plug, vacuum leak at intake, fuel injector failure and last no/low cylinder compressio.

SOURCE: Fast Idle Problem With 99 Isuzu Rodeo V6

Hi.

If problem is only on startup and when idleing, then the problem is likely IAC system, also a vacuum leak will cause the same problem.

If problem is not only on startup and idle, but also when driving, then MAP sensor and EGR system must be checked.

Check also accelerator cable state and setting.

The first thing to do is pulling out the OBDII fault codes stored in the ECM. This is done connecting a code reader to the ECM diagnostic port. The job can be done for a small fee at any local garage, and it is done for free at AutoZone.

The codes will help locating the problem.

About possible faults:

Problem is stalling when idling and during startup, but engine idling fast all the time. Problem not starting at times it is due to the fact that the wrong mixture is being sprayed, this is probably causing flooding and misfire. Since the CEL is on, one of the codes returned is probably misfire.

Check accelerator.

Check IAC system. This is composed by a valve and a solenoid that check and control amount of extra air air when the engine is idling. The IAC valve is located on top of the throttle body.

Check the vacuum system and try cranking with gas tank cap off. Vacuum system is tested using an hand tool gauge onvacuum lines while spraying card cleaner on the hoses (or heating them with a torch). If there is a leak, pressure will go up. A big leak will also do hissing noise, and will often result in a lean code when doing an OBD code scanning.

This kind of symptoms can also be caused by weak wiring to MAP/MAF sensor (MAP in this engine).

If the car also drives very rough and is revving up and down in a weird way, check the EGR valve.

As first thing I would do a code scanning. This car is OBDII. The scan can be done for free at the nearest Autozone, or for a small fee at any garage.

If you get any OBDII code from the scan, report it here, so that we can individuate the possible reason for the problem.

If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.

Regards.

Ginko.

Smoke near the passanger front wheel


pull off the tire and remove the rotor. clean the bearings with carb cleaner and look to see if they have signs of heat stress(dark blue/purple disscolorations) if so replace both inner and outer bearings. also look for the same discoloration on the rotor. If it has the color, your brake caliper is hanging up. It also may of been something as simple as blown grass od weeds caught in the rotor and burned off when it got hot, thus the reason you havent see it since.
