Hyundai Sonata - no injector control. Wiring harness is stretched. Interesting case.
The Hyundai Sonata doesn't run on gasoline or LPG, it's misfiring badly, there are numerous wiring issues, and the wiring needs to be repaired after the LPG installers. The ECU needs to be opened. The problem resolved itself, but the misfiring was caused by different compression levels between the cylinders.
