    mine at idle is fine and under hard acceleration it runs just fine but on initial acceleration just off idle it spits and sputters then as I get up to steady speed it spits and sputters. What gives?

Take your car for a tune up
if they are carburetor type motors you may need your carbie cleaned and a tune up
if you clean it your self with carbie cleaner it may increase in idle speed this is nothing to worries about it is a simple adjustment
with a carburetor type motor they tend to idle higher when their cold this is the automatic choke kicking in and normally it should happen till the car is a bit warmer and the accelerator has been depresses
although a car should idle at 800 rpm my paddok car dose when it is cold it idles at 1200rpm i like it this way as the car warms up quicker as i will not drive a car while it is cold
hope this helps

High idle benz 190e


Could be a defect in the ECU. But 1000rpm is not that high my cars normal is 1000rpm. but some older models were about 700rpm
The AC rise is normal. You may want to have a OBD II check by your garage or you can buy a unit to do this. It will scan the sensors fitted for any problems.

Since day one, my 2007 Dodge Ram Hemi always starts like its in a cold engine cycle. In other words, it starts at a high rpm and steps down in increments for about 20 seconds. Hot, cold no matter. It...


Yes, it is normal for a vehicles idle to be high when first starting up, no mater what the temp. If it`s already warmed up to operating temp, it will still have a high idle for a brief moment when starting. Usually this is the IAT (Intake Air Temperature) sensor. Located in the air duct down from the air filter, and before the throttle body.

Main proplems from IAT sensors are to low of an idle at normal temp, or the idle never comes down after warm up.

Your gas milage problems would stem from Oxygen sensors, plugs, wires, timing, etc...

Here is a quick test, just incase your OBD II (Computer, PCM..) memory module is not working properly. With the engine running, using the tips of your fingers, tap on the PCM, if the engine stumbles or stalls and sends troubles codes that light up your check engine light while tapping, if it does, check to make sure all wires are securely attached to it.

I have a 1984 ford f150. The truck idles very high when in park but when you put in drive or reverse it goes down to normal. It has duel straight exhaust on it and I wonder if that could be the prob. Idk.


you didnt say if it was happening only during the initial warm up of the vehicle or all the time. if it is just during warm up this is not too unusual as long as the engine isnt racing. if it is just a "high idle", say arround 2,000 rpm's its normal. the idle would usually go down as the vehicle reaches operating temperature. when you put the vehicle in gear, you are actually loading the engine slightly, thats why the idle comes down then. when in park the engine has no load on it so it is free to rev a little higher at these times. if it a at a high idle constantly, then i would start looking for sticking throttle cable, binding throttle plates, ect and remedy the problem. this should not have anything to do with the dual exhaust.

I have an 02 wrangler and the oil preasure goes down when Idling is that an oil pump going bad?


First we would need to know when this occurs. Asuming the oil level is at the full mark!. If the pressure goes up during acceleration and down at idle when engine is fully warmed up, then this is normal. An engine requires 10 psi of oil pressure per 1,000 rpm ( ex. 20 psi at 2,000 rpm, 25 psi at 2,500 rpm, and so on ) . If the gauge is moving back and forth erratically at idle , i would say the gauge is bad. If it drops to 0 while accelerating I would say your oil pump is bad. If from time to time it seems to work and other times it seems not to work, I would say the oil pressure sending unit for the gauge is bad. If the pump failed you would start to here a Knocking noise from the engine in a short period of time. Use the above scenario's to narrow down what it may be.

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.

Engine will not idle until warm. then it is just fine


This is normal, as long as the rpm's are not above 2000, this is to heat the engine to it's operating temperature quickly. Once the engine is warm, the rpm's will drop to 600-800RPM.

High idling at low temp.


Hi,

Offhand, yes this would be normal. The high idle is brought about by the auto choke whose purpose is to hasten the reaching of operating temperature of the engine. The fact that the idle RPM goes down after some time is a good indicator, it tells us that the auto choke is working.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
