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.

The check engine light on a 2001 beetle read code PO118 engine coolant temperature circuit high input. what do i do?


16502/P0118/000280 From Ross-Tech Wiki Jump to: navigation, search Contents [hide] if (window.showTocToggle) { var tocShowText = "show"; var tocHideText = "hide"; showTocToggle(); } 16502/P0118/000280 - Engine Coolant Temperature Sensor (G62): Signal too High 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 idle rpm will often 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 warm-up.
  • Diesel Engines: Glow plug indicator may be on for a longer than normal time or at ambient temperatures where it shouldn't come on at all.
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 many cars between MY 1995-2002 the G2/G62 had a bad reputation for failing often. The original G2/G62 sensor is black and the improved replacements are green.

The engine light


3000 rpm? This is pretty high for idle. You need to have the stored code read from the ECM. Usually this is a simple O2 sensor but with it racing to 3000 rpm I would have this diagnosed by a tech at a shop.

2500 to 3000 rpm idle


Change your Thottle positioning Sensor. My 93 lesabre did the same thing and i changed the TPS and it stopped.

Ngine over fueling at all rpm, rough idle, heavy fuel consumption

Engine starts,reaches high rpm,then slowly returns to a rough idle, misses badly,no backfire,surges as if searching/adjusting air/ fuel/est,timing light shows mark constantly changing/erratic,engine then...


Vacuum leaks. Check all hoses and intake bolts. Leaking EGR or plugged PCV valve. Air filter plugged. Leaking head gasket. Worn timing chain. Camshaft lobes worn. Valves burned or leaking. Fuel idle control system or sensor. Good luck!

3.3 L 97 Grand Voyager engine won't idle revs stay at 2200 - 3000 rpm


Possibly the oxygen sensor. Had same problem with my Accord, had oxy sens replaced and that not only fixed the problem but I got better gas mileage after that.
