Adjust the idle screw.
Needs a Tune up
NAPA and Precision Tune and Auto Zone have a free analyzer check. Use it.
Might be time for a tune up, new plugs, fuel filter, pcv valve, cap and rotor and wires if aplicable.
Could be the mechanic set the throttle control too high, so your car idles at a higher RPM than it used to. Timing was set wrong. your car should be better after a tune, perhaps the tuner made a mistake or did not do the tune correctly
that is a computer problem you will need the proper reader for it and that is about 4000 so just take it in it is only about 40-60 dollars and they will tune it right
how do i tune up my 5a toyota engine
To turbocharge a 200cc single-cylinder carbureted engine, you need to select a small turbocharger that suits the engine's displacement. Begin by ensuring the engine can handle the increased air and fuel demand by upgrading the fuel system and carburetor to accommodate higher flow rates. Install a boost controller to regulate the turbo's output and add a proper intercooler to cool the compressed air for improved performance. Finally, make sure to tune the engine to optimize the air-fuel mixture and ignition timing for the added boost.
I perform diesil engine tune up to avoid engine trubol
More than likely... Tune up, or vacuum leak
It probably needs a tune up. My 1998 Mazda 626 was idling very rough, so I did a tune-up by replacing the spark plugs and wires. This made the engine run better, but the rought idling continued. I took it to my mechanic, and he found a vacuum leak somewhere, and $270 later, it idles smooth as glass
I've had this problem a couple of times with my 96 Ford Explorer. Either: 1. The car needs a tune up 2. A sensor is out and the car needs a tune up 3. Something is wrong with idle . . . needs to be checked The real answer is that you need to get to a mechanic asap . . . When the idle was loose, the car would die, but when a tune up was needed it ran rough without fully dying . . .
