chech engine light is letting you know that the idle air valve has been disconnected. looks like you have a bad idle air valve.

Rpm does not drop below 1000


No,only on carburated engines it,idles down to the set point,on yours,it's fuel injected,pushing gas pedal won't kick idle down,should go down after a certain amount of time,does it automatically,If you start and drive a 5 mile ride and stop at a stop sign,it should idle at it's set point if there's no engine problems,which may be.5 to .7 on your tac.When you normally first start,it will idle between 1000 to 1200 rpm's,don't push on gas,let idle say 15 seconds,put in drive and go.

89 cutlass cierra crank but wont start when wet out unless gas pedal is pushed


This should be a drive by wire vehicle meaning it has a cable for the throttle body. First thing would be to see if any error codes can be pulled up (most parts stores will do that for free.) Drive by wire versus the late model that use electronic control for the idle have a IAC or idle air control which when first started controls the idle air intake--all air is run by it to idle the vehicle when cold--

Usual symptoms are rather high idle when cold engine or even idle and RPM jumping up and down and stalling when cold.

Another way if idle does drop when cold is tapping the gas--engine will still run until hot. Means not usually a fuel pump issue.

You could also have if the vehicle is fuel injected a dirty Mass air flow sensor, a throttle position sensor, etc.

These can be if the vehicle has them cleaned using a special zero residue spray cleaner.

First have it scanned to see what if any errors it shows--the computer.

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.

MX-3 with V6 Manual transmission. Engine idle revving up and down


You should check your engine's AIR hoses that are connecting to the airbox. sometimes a simple airleak will be enough to alter your idle. Specially when its cold the car will already idle rough ( I know im canadian lol). So go check your air hoses ;)

2002 Wrangler 4.0 idles too high in park.


normal for an engine to start at elevated rpm and then die back as it takes a few seconds for the ECM doing it's sensor checks and idle back to the correct idle speed
check the idle rpm with an external rpm counter as most in dash units are inaccurate at rpm lower than 1000
as for the temperature
If you have a climate control module, it uses a mixture of heater and ac to maintain the temperature that you have set
so check it for operation
