compression test, coil issue,

Did you scan for any trouble codes? Whenever the 'CHECK ENGINE' (Service Engine Soon) light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE the problem and perhaps fix the problem.

The problem you describe has many possible causes. Any number of engine management sensors (which are starting to go bad) can cause this problem, the fuel pump is starting to go bad, the engine computer, wiring, connectors, etc.. the list goes on and on. My experience tells me to tell you to take the vehicle into a Hyundai Service Center and try to get it diagnosed. If successful, they'll give you an estimate of repairs (parts, labor, tax, time-frame, etc.). This way you'll know exactly what's wrong and what's required to fix it. Now, since the problem is 'INTERMITTENT', that makes it tough for the technician unless he/she can discover any DTC (Diagnostic Trouble Codes) stored in the computer (ECM - Engine Control Module) - Did the 'Check Engine" light ever come ON? If so, this will help narrow the search and diagnosis.

The check engine light comes on because of an error detected by the car's computer. You need to have the specific error code read with a code reader/computer.

often that problem can be cause by the crank sensor, check engine light will come on,if it is scan code to make sure ,it will point to problem area

if it has a check engine light the simplest thing to do would probably go to auto zone or advance and ask them to do a code check,its free and will probably tell you the problem and take allot of the guess work out of it.

could be a cat. or a bad maf sensor
