Question about Hyundai Sonata

1 Answer

I've been having problems with my Hyundai Sonata 1999 with a 2.4L 4 cyl. Running rough when started. Have to push gas pedal to start or stalls after running for a few seconds.. Sluggish/jerky starts when leaving for work or after. Runs fine after warmed up. At highway speeds (75 MPH) I get a jerking like the engine is missing or not getting enough fuel and very slow accelleration

Could be a few things the start up could be the idle air control sensor (my first thought), the coolant temp sensor for the computer might be a secondary thought for the engine being cold if the computer thinks its warm. that would be the first 2 places i would start without a check engine light or code to reference

2000 hyundai sonata.. P0300, P0110 and P0102 codes..


Higher octane gas 93 with some good octane boost in the black can at autozone cost about 7 dollars or a bottle of 104 octane boost. Change the fuel filter. Probably only one coil pack is bad. The OBDII reader should tell you which one was a misfire.
