SOURCE: IDLES FAST WHEN STARTED, FOR 5 MINUTES THEN DROPS

It's the choke doing tis job. It reduces the amount of air to the engine to help it start/warm up. As the engine reaches a good operating temp it will drop the RPM's. Some times they do get stuck, so some cleaner wouldn't hurt. Spray it into the throttle body while the engine is running. Also the O2 sensor could be bad.

SOURCE: I have a 1987 Susuki Samurai, 1.3 engine. Cold

Yeah it sounds kinda high. There is no adj except for the idle screw on the throttle, the computer does the rest, if it has one. If not, then you can adjust it some how. If carbureted, check for 2 little screws in the front, and check the choke, If throttle body, then just the idle screw, the idle should be around 1000. Hope this helps.

Idle too high


Sounds like your idle curb sensor is shot. Did you replace the shift sensor by any chance, this also could make the vehicle shift hard. Did you change the fluid and screen when the trans was replaced?

I have a 1993 Ford Explorer that goes into high idle when I put in gear. It does this when the engine is hot or cold.


On some cars there's a speed sensor on the clutch or transmission. That might cause an idle problem.

I have a 96 nissan maxima. It idles at about 1300 in park and 900 in drive. A friend suggested changing the spark plugs. Does this sound like a solution?


No spark plugs only produce spark to ignite the fuel mixture and do not control idle speed. Run fault codes to determine if there is a sensor fault as it should be idling around 900 rpm at idle and stay close to 900 in drive as the ECM will adjust the idle rpm to compensate for the extra load. Nissan maxima use special plugs that do not need changing

My 1997 Chrysler Concord idles at 2500 to 3000 rpm when first started and when it warms a little it idles at 2000 rpm and stays there. When I start it right after I turn it off, it starts at 2500 rpm then...


Maybe a short to the TPS or something shorting it out. There's also the IAC that really controls the idle but usually it will cause the RPM's to go up and down a little erratic if bad. The MAF sensor can cause major problems as well but since you already swapped the TPS and it helped and then stopped I would focus on that sensor and especially it's wiring to and from the ECM. Be careful with the sensor signal wire to the ECM can blow it if more than 5v passes or spikes.

Tachometer reads 750 -850 rpm at warm temp. what should the idle speed be?


For this car it shouldn't go over 900, but should have a good idle around 700-800. It sounds like a lot, but my expedition idles at 700-900, depending how fast i want it to heat up.
