Clean the throttle body and service the idle air control valve assembly.
Remove the key from ignition switch, remove the negative (-) battery terminal for five minutes and relearn the idle air control valve. You can read my previous posts about how to do it.

Hello all I have an accent 2005 CRDI. It starts in the morning After a little ride It stubborns to start and I can see lot of smoke and the mechanic says it is fuel injector problem. Please advice .


Venkata, According to Injectorrx.com: "
Fuel injector symptoms for bad, faulty, dirty, clogged, or leaking injectors are :






  • Starting issues


  • Poor idle


  • Failed emissions


  • Poor Performance


  • Engine does not reach full RPM


  • Increased fuel consumption


  • Rough engine performance


  • Surging and bucking under various throttle loads


  • Smoke from the tail pipe


  • Engine Knock or Detonation which can lead to catastrophic engine failure


  • Pollution"



Venakta: I have had very good luck with a fuel injector cleaner sold by Advanced Auto called KX44 but some people like Seafoam. It is a cheaper place to start than with a mechanic.

3. Check fuel pump pressure. (44 Psi - 49 psi)
4. Remove the negative battery terminal for 5 minutes.

Just started idling rough, sometimes stalling


Shot in the dark here without knowing the vehicle but it could be an Idle Air Control valve starting to fail. An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air. An idle air control motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the idle air control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor. To check the idle air control motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the idle air control should move in or out. If the idle air control motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the idle air control motor is removed clean (use aerosol carburetor cleaner) the passages the idle air control uses to control idle air speed, also inspect the idle air control for a build-up on the seating (pointed) end and clean as necessary.

P0108 do i need to change my intake gasket? starts and idles poor and sometimes dies in morning may not do it for days, once it warms up it runs great!


It's entirely possible the intake manifold gasket has failed. An engine vacuum leak is a potential cause of the P0108 code.

Idle is too low, car dies, engine runs fine


An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The car computer or ECM (electronic control module) receives information from various sensors and will output signals to adjust the IAC motor in or out to adjust engine idle speed by controlling engine idle air.
An IAC motor is highly susceptible to carbon and coking build up; if an IAC goes too long without cleaning it can cause stalling and poor idle quality. Some cars are designed with a large vacuum transfer hose that connects the intake manifold to the IAC (idle air control) motor. If a broken or dilapidated these vacuum lines can cause the engine to lose vacuum which will allow the engine to run rough and die. 
Inspect all engine and accessory vacuum lines to look for missing, torn or dilapidated lines and replace as needed. To check the IAC motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the IAC should move in or out. 
If the IAC motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the IAC motor is removed clean (use aerosol carburetor cleaner) the passages the IAC uses to control idle air speed.

Good luck and hope this helps
