The EGR valve is closed when the engine is cold and should open when warmed up. Have all componets check to see if they are functiong correctly. Auto Zone provides a free computer scan at no charge . They will avise you what is in need or replacing and how much for the part. These parts are easily installed too

My 1988toyota hilux 4ycpetrol runs rough when cold but fine when warmed up


The cold start circuit is not working properly. Chances are that the gas or air mixture is not correct when you initially start the car but fine after the engine warms up.

My 98 Honda Accord Vtec 4cyl. eng is starting fine, but after start the idle dips a few times and regains for approx. 3min. If I drive without warming up the car will hesitate and the gas pedal will delay...


Seems like the coolant temperature sensor is giving the computer erroneous readings, and it is not adjusting the fuel mixture properly for cold engine operations. You should have the check engine light on, indicating this malfunction. The idle fluctuations are normal. The engine is trying to die, from the improper cold mixture, and the computer (ECM), recognizing low idle speed, is sending it back up. Another possibilty is that the butterfly on the throttle body is not closing completely, to allow richer mixture needed for cold starts.

Car gets warm and starts hesitating on acceleration


Hi,
this could be something in the fuel pump. As the cold motor draws more fuel, it may just be just ok for the engine, but after it is warm, it draws less and may "suffocate" it that way. Same goes for air filter, take a peek if it is not ready for replacement. Has this happened suddenly, or has it occurrend during a long perion of time?

99 S-10 Engine hesitates only when warm


If it has miss and hesitation only warm not cold you may have a coolant temp sensor problem . but if the service engine soon light is off i would chek ignition system(plugs, wires ,boots).most likely one of the cylinders missfires when hot.
