    The problem you describe could be caused by many different things, and I don't like guess work.

    Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. Electronic Throttle System is my guess.

Check the airfilter...Go to AutoZone and buy a can of "SeaFoam" ($8) and follow instructions, possibly a cheap fix for a faulty O2 sensor.

Car stalls when ever you come to a stop or slow down a diagnostic revealed several possible causes 1. knock sensor 2. 02sensor and 3. idle control


Knock Sensor - is not an issue
O2 Sensor-just sees the condition of exhaust, during the stall & sets a code

I would look at the Idle Speed Motor, TPS Sensor,even vacuum leaks,Egr Valve.
Don't know your veh systems, Hope that helps some.

1990 full size blazer starts fine idles then dies


sounds real easy either a bad idle air control solenoid or more likley a blown throttle body gasket. to test fro a blown gasket, with engine running and cool spray carb cleaner or brake cleaner around base of tb were it bolts to intake. when it hits the bad area, should idle down and be normal for a second or 2. iac is possible,try this first since its so common and let me know

My hyundai is making a rattling noise


that sounds like what we call "spark knock" that occurs when u accellerate quickly, but yes it will go away in a few seconds when the computer detects this condition. with the economy the way it is it will be more expensive, but try running higher octane gasoline in it, should cure this condition. hope that helped you!!

I wanna know where the location of the fuel filter of my SONATA 2006 3.3L. and also i have got a problem that since two day my car started hanging while driving and especially when i am driving in a low...


First: The fuel filter is in the fuel tank attached to the fuel pump - no maintenance schedule required. Second: Engine performance problem - did the 'Check Engine" light ever come "ON"? Is the vehicle still under warranty? If so, take it to a Hyundai Service Center and have them diagnose the problem. They'll give you an estimate of repairs (parts, labor, tax, time-frame, etc., as well as wether or not the problem can be fixed under warranty). Good Luck.

High fast idle at start up.


On most newer cars there is a fast idle motor controlled by the computer that will hold the fast idle till the engine reaches a preset temp in the computer then the engine should drop down to the set idle according to specs for that car. If the oil pressure continues to stay low after the idle goes down you may need to replace the oil pressure sending unit or if worse case the oil pump.
