The maf on it isnt used a maf only a temp sensor the software change made the syatem speed density controlled fuel.. but if you have a idle probel it may just be the Idle Air Control Motor or IAC try to put foor on the gas pedal a little whne cranking see if it fires right up if so suspect the IAC.. is if still cranks long time try the fuel filter but those usually will make lack of power before you get a hard start issue.

Any chance this fault has happened just after topping up engine oil. Oil filler cap not seating properly will give same symptoms. The cap and surround have arrows that need aligned in order for it to be fully seated. Check oil cap first.

2006 Chevy Colorado 2.8 4 cyl. Engine is surging under normal acceleration. It has about 85K.


Clean the MAF sensor and the throttle body. Plus the Idle air control motor. Use a toothbrush with brake clean. Just spray the MAF with brake clean both ways..

Error codes P0507 and P0102 after replacing MAF sensor


P0102: you need to make sure the sensor is clean; sometimes it get dirty as you are working on an old car. Check the voltage manually. Make sure there is no air leak near it

P0507: high idle... this sounds like a vacuum leak. get starter fluid and start the car. Spray around and check for change in car idle

1990 honda accord surges at idle, what can cause this?


It is likely a vacuum leak (from a hose or the intake manifold), or a sensor is not working properly (like the throttle position sensor, MAF sensor, idle air control ).
Spray carburetor cleaner around suspect areas to find a vacuum leak. The spray will be sucked into engine and raise idle. Spray around the intake manifold where it mates to head for leaks there.
Also check for trouble codes. Maybe a sensor threw a trouble code.
Good luck.

2004 Toyota Corolla, dosnt Idle at all, have to give it gas


I would start with cleaning the MAF sensor and checking the resistance with an ohmmeter. Any shop specializing in imports should be able to tell you what the acceptable resistance parameters are. Use carb cleaner on the contacts, and let it air dry. DON'T try to towel dry it, as this could irreversably damage the sensor. If that doesn't work, I would check the throttle position sensor.

I need to clean my Mass Air Flow Sensor on my 92 Chevy Corsica and am not sure how.


I can't tell you the exact procedure for disassembling the MAF in a Corsica, unfortunately. I can tell you that if you are able to locate and disassemble it, you should handle it with extreme care. The monofilament wires are extremely easy to break. Do not use any object to touch, wipe, brush or scrub at them. I personally don't recommend cleaning the MAF on any vehicle, but if you find that you must, you should use ONLY an electronic cleaning spray. CRC sells an excellent electronic cleaning spray that is non-damagine to plastics. Simply spray the MAF down very thoroughly with the spray and allow it to air dry before reassembly. Beyond that, anything you do to it would be likely to damage it. Any other types of cleaners, such as carb cleaner, would be likely to cause the plastic parts and other delicate electronic components to break down and be ruined. Good luck and let me know how it goes!

Dodge ram 1500 engine rpms surge at freeway speed


those sensors could cause the issue, clean the MAF 1st, also clean the idle system using the following procedure, the IAC can cause cruise surge. I use this to cure these problems all the time.

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve (IAC) and throttle valve, they get full of gunk 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.

Wont stay running


You may have a defective idle speed control valve. Clean it first.
