1997 acura cl 2.2 revs up to 1500 rpm and down to 1000 rpm just several seconds after start


Cars are design to run at a higher idle at start up to warm them up quick. There is a sensor that reads water temperature and tells your car's computer how fast to idle. Your RPMs seem slightly high but not out of the norm. Does idle ever drop to around 600/800 after about a minute? If not, your engine temperature sensor maybe defective.

My 2.0 engine idles fast on a cold start. Then idles down after warming up.


This is normally the way it is suppose to work. You need to have the RPM measured for High RPM and duration. What you are describing is how an electronic choke is suppose to work.

The errors would be how high the RPM goes and for how long it lasts. When cold the RPM, fuel mix and timing are changed to give a rich fuel mix. As the O2 sensors warm(Could be defective) they signal the engine to lean up. The water thermostat also has something to do changing the engine to a lean running slow condition.

If obtaining heat from your heater seems to take Forever, the thermostat could be weak. This would coincide with the engine continuing at a high RPM longer because it is not warming up.

Idles fast problem


That would be your engine "choke" functioning. It's not a problem. The choke engages when engine is cold and shoots extra fuel to the cylinders to idle the engine up especially in cold with. Once the engine has sufficiently warmed up, the engine will idle back down.

Chevy Malibu Cold Idle Problem


Check the water coolant thermostat. If it is stuck in the "open" position you are heating up all the water in the coolant system and this will take time. The thermostat keeps the water in the engine until warmed up to almost normal running temperature, only then does it allow the coolant to enter the radiator.

Good day: I don't accept that cold starting an engine at 2000 RPM is OK. Those immediate revs on a cold engine are wearing out parts that need oil lube and warm-engine clearances. Is there a simple way of...


I have heard that Fords theory behind that is to supply maximum oil pressure to moving parts sooner. All the Ford products do this and the motors last well into the hundreds of thousand of miles. I wouldn't be to worried about it since there is no issue with it to my knowledge and there is no way to limit the cold start RPM's.

Cold start warm ups are a thing of the past. Better lubricants, engines, fuel injection and other computer controls have made start ups easier on the engine. 30 seconds is barely enough time to warm up anything and after a few seconds oil has already reached all of its intended lubricating points. That first few seconds is the hardest on the engine. Regardless of how any RPM's it is turning.

Error code po0117. Vw beetle


16501/P0117 - Engine Coolant Temperature Sensor (G62): Signal too Low Possible Symptoms
  • Difficulties with starting a cold engine.
  • Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
  • RPM at idle is irregular.
  • With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
  • With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
  • Bad acceleration during warming up.
    • Diesel: an indication is extreme long time burning time of the glow indication light.
Possible Causes
  • The electrical signal coming from G62 is too low
  • Wiring and/or connections faulty (short circuit?)
  • Engine Coolant Temperature Sensor (G62) faulty
Possible Solutions
  • Check wiring and connections
  • Check / Replace Engine Coolant Temperature Sensor (G62)
Special Notes
  • In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.

1993 chevy pickup hard starting and tach oscilates 200 rpm up and down


sounds more likley you have an air leak this will cause bad starting as it is sucking air in instead of fuel when its cold and wnen it warms up idling will be eratic and misfire check all hoses gaskets relating to the inlet manifold or if its done that kind of mileage crankcase pressure could be the problem but i suspect an air leak yates210456
