1998 suzuki swift idle problems 4 speed 1300cc


no engine type stated, there are 6 engines used.
but bad idle is caused by 2 things.
  • misfire.
  • or lean AFR, lean fuel mix.. causes HUNTING
the ECU can also cause the hunt if it can not hold hot idle to spec.
most cars is 800rpm.

I have an 03 f150 with a 5.4 engine. Truck starts and runs great when cold. Once it is warmed up is when the idle problem shows up. If I stop to run into a store or get gas and then restart the warm engine...


The symptom of which you are describing is known as "hunting"
for idle.
You need an idle air bypass solenoid, otherwise known as an IAC. The part mounts right on the throttle body. Sometimes they can be cleaned, but for around fifty dollars, I would suggest a new one.

I have a 1988 F150 with a 302, the truck has a hard time finding a Idle


Many idling problems such as yours can be resolved by simply having the car tuned up ie , new air filter, change all spark plugs, oil change, etc... you'd be surprised by the outcome! Good luck.

I wish to adjust the idle tickover speed a wee bit on a 2007 Ford Transit 2.2 Duratorq engine. It is currenlty ticking over at approx 800 rpm and is hunting at this rev. If I could raise it a wee as I do...


First ensure that the throttle interior is really clean, a surface layer of grime can upset the ECU's ability to meter and govern the air entering the engine. If the throttle body interior is found to be really oily and dirty check on the idle air control valve and make sure that it too is cleaned up. Next put the ignition switch in position 2 (on, but no start) and depress the accelerator fully and release. If there is an issue with the throttle position sensor this procedure can help the ECU relocate the throttle plate position. Start the engine and if it is still hunting locate the air mass meter (AMM) on the air ducting immediately next to the air filter and disconnect the electrical connection. Does this remove the hunting aspect?... the rev speed might change but for the moment concentrate on the evenness of the tick-over. If the idle is even when the AMM is disconnected but hunts when connected then look at replacing your AMM. Try spraying the AMM with no residue electrical cleaning spray to see if this improves matters.
