I had my hand against the engine well and gotten burned then I realized that this little silver relay was fire hot. I believe its a drop resistor? or oem or jecs sensor


pull it out and if it has 4 or five pins it is a relay an is faulty
resistors will be hot as that is what happens when they change high voltage to low voltage

P1294 Target idle not reached


You can take an old spray bottle and fill it with water. Then with the engine idling or the idle raised to above 1200RPM, spray a water mist over the seams and Vacuum lines. Also spray around the Brake booster.
If there is a leak, the water mist will cause a change in the engine RPM. Then fix the source of the leak. You probably should check with Autozone, Advance, or Oreilys for the part. You can see what it looks like at these 3 stores or look up the part with the Web Browser.

Sometimes the passages that the idle control valve use can get dirty and the valving can freeze up. Depending on condition, WD40 sometimes can both clean and free up the parts. You can ask the Autoparts place what you need in the way of gaskets. The part should be somewhere in the intake manifold. I usually work on the Ford family of Brands.

Once you work on this part, any of the 3 places can clear your onboard computer.

I have a 1983 Ford ranger with a 2.3 4 cylinder, yesterday, after replacing a lot of parts, it finally was running great--no miss or rough idle. Until I revved up the engine. Then it started running...


Hello, If this is a push rod engine I had an identical problem with an engine in my 1988-1989 Jeep Wagoneer. It was a Buick V-8 and behaved exactly like your Ford engine.

On my engine it was weak valve springs. You could take your thumb and push on the valve spring while the engine idled and the engine would miss out. Turn it off and start it up and it would idle smoothly, rev it up and let off the gas and it would miss out and shake. You could also have hydraulic lifters (check your model) and they could behave like this. At idle the lifters would pump up, but the lifters may not refill fast enough to work the valves smoothly.

If you have hydraulic lifters they must be centered in their travel to pump correctly. Even if you have solid lifters the valve adjustment can affect engine performance.

Sounds like your Mass air flow meter is bad. Seems like they changed your knock sensor when they should've warmed the car up to figure out it is the MAF sensor that's bad. It's a common problem on that generation Maxima.

The engine will idle around 700 rpm when it is working properly. Sometimes it will idle around 2500 rpm. If I turn off the engine and restart it that somtimes will help. Looking for guidance as to what...


High idle is usually caused by a failing idle air control valve. First remove the connector from the valve to see if there is any corrosion or looseness in the connection. If the connection is good, remove the valve and clean both the valve and the passages in the throttle body. If you have an ohmmeter you can test the motor windinds in the valve using the procedures pasted below from autozone.com. If good, reinstall the valve. Hopefully this will cure the problem. Let me know if you have any questions and thanks for using FixYa.

IAC is the cylindrical part on top in this picture.

IAC motor winding test procedures:
  1. Attach an ohmmeter to the top two prongs of the IAC valve, terminals A and B.
  2. Inspect the ohms, measurements should be between 50-80 ohms.
  3. Repeat the process for the two lower terminals, C and D.
  4. If the sensor does not come within specifications on either of these tests, replace the component.

Poor Idle, dies at stopsigns


I have used this fix for your problem for 20 years.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
