Engine is difficult to start when cold

  1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
  2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
  3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
  4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
  5. Check for a failed coolant temperature sensor, and replace if out of specification.
  6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.
Engine is difficult to start when hot
  1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
  2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
  3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.

2004 mazda mpv engine racing and cooling fan not working


coolant temp sensor tells the computer how hot or cold the engine is so it can regulate the idle and fuel mixture, when it fails there usually is no cooling fan and you will have trouble starting the engine and keeping it running.

When i start the car the engine racces to 2500 rpm why?


This is normal idle control strategy, it races up to keep the engine from stalling out until it stabilizes, if it doesn't drop back to normal idle speed of about 600 RPM after a few seconds (longer on cold start up) then you need to have the electronics tested to see what the problem is.

Lately hard to start and idles roughly while cold


If it has not generated a "check engine " light, troubleshooting will be more difficult. You have a Cold Routine for starting that is triggered by temperature. It is possible that a temperature sensor is not good and therefore the Cold Routine is not cycling.

Contact Autozone, or Advance autoparts for a scan or talk about this part that you may need.

This must be an idle control valve. Try cleaning electric contacts. You could try removing, thoroughly cleaning it and grease it. If this doesn't help replace it.

If it runs fine and the idle is the only problem you could try idling it up some with the idle set screw on the throttle body it sounds like it may be a little bit out of time those toyotas have a fine lins on the timing.

When warm the car does not idle. when its cold it starts and drives fine. when it warms up it shuts off and idles rough.


Find the egr valve on the intake. Look up on the internet what it looks like because it is difficult to describe. There will be one vacuum hose attached to it. Start the car and let it warm up. when it starts to hesitate remove the hose. If the engine holds idle, you need to replace the egr valve. The egr (EXHAUST GAS RECIRCULATION) valve allows the engine to re burn the exhaust gas when the engine is cold to clean up the emissions at the tail pipe. They tend to get stuck in one position from carbon build up and need replacement.
