Engine Performance problem
2006 Other Kia Models 4 cyl Front Wheel Drive Automatic 45000 miles
My Kia Picanto was modified to contain dual system, gasoline and CNG. It starts in CNG fine, but when in gasoline the vehicle does not want to start easily in one go when cold. Even after starting, it tends to go off as soon as I put the gear in Drive Until the engine has heated up sufficiently. The car is hesitant whenever I hit the gas paddle and wants to stall. However, as the engine heats up the symptoms get tolerable.
I have changed the Injectors recently, it has not helped much.
Can you give me some clue about where to look next?
