You are going to want to have the control module checked out. It regulates among other things. The fuel flow with regard to demand, ie... throttle position, air intake, speed, altitude, etc... And the companies are also designing some key parts with what is called "planned obsolescence". This means that instead of tinkering with it in your garage. You have to take it in for diagnosis and repair. Generating more "after sale" revenues.
Sorry about the mini rant. I have issues. Anyway you also should check two more things before you go to the shop.
1) fuel filter. (they do need changing every so often)
2) Actual fuel you are using!
And you can do that in your garage!
They quality of fuel is questionable nowadays. Within Two tanks, my performance was noticeably affected. Why you ask? I moved to Oregon., thats why! The fuel here is lousy. So we are always looking for the little private gas spots that DON'T have gas additives the big companies put in there.
Hope this helped.
Wheels down,

SOURCE: engine check light is on my mitsubishi chariot

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. There are test that need to be performed the find out the cause. The light will stay on until the problem is solved.

SOURCE: engine speed surges

Surging engines in lawn mowers are usually related to a lean fuel/air mixture. With today's environmental concerns, the carburetors on these engines are set with a very lean mixture (to reduce air pollution). Furthermore, they usually put limiter caps on the carburetors where you cannot easily adjust the mix to get the engine to run better.

If there are adjustment screws on the carburetor, try turning the high speed adjustment screw a bit counter-clockwise (if the limiter cap will allow it). This will enrich the fuel/air mix a bit and might help the engine run a bit better.

Testimonial: "Thanks, I think I can figure out which is the High speed jet, it's the other one besides the one that restricts the throttle from going below a level."

P0508 code on 2001 Honda CR-V how do I troubleshoot


P0508 = Idle Air Control System Circuit Low

Engine Light ON (or Service Engine Soon Warning Light) - Engine hard to start - Rough or erratic idle speed.

Dirty throttle body - Electric throttle control actuator misadjusted or damaged - Faulty Electric throttle control actuator - Intake air leak - Poor electrical connection to the Intake Air Control (IAC) valve.

If there are no intake leaks, clean throttle body, adjust engine idle and erase engine code. If the code comes back you may have to replaced the Electric Throttle Control Actuator (Motor) to repair the problem.

I hope this helps!

My 1992 chev lumina apv van stalls everytime i put on the brakes at every red light it restarts after no codes are coming up what could it be?:

check to make sure the power brake booster is not leaking, do this by starting the van and just let it idle in park and push the brake pedal if the engine stalls or surges or you hear a sucking noise under the dash then replace the power brake booster if there is none of these systems then replace the idle control motor. GOOD LUCK

Check the oil pump and the oil. If the oil is too thin or the oil pump is worn, that can cause untold damage to your engine!

Engine light is on idle is high and low took it to a mechanic replaced idle control motor worked for a day or 2 and started to do the same thing again and they reset the code on the computer

If the engine is surging fast and then slow every few seconds it is most likely the air mass sensor MAF. It is sited on a collar on the air ducting just after the air filter box. Start the engine and leave it it to idle. To confirm the diagnosis there is a simple and free way to check.Start the engine and then disconnect the plug to the MAF. If the engine now begins to idle evenly (it might be faster or slower than usual but no longer surging) this indicates that it is the MAF at fault.
