Question about 2000 Hyundai Elantra
I am still getting the misfire in cylinder 1 and i changed the coil pack. i also checked the fuel injectors. is there anyway it could be the computer or could it be something else. Thanks for you help
If you just changed the coil pack by itself there is a good possibility that you may have had a bad spark plug or plug wire that contributed to the early demise of the coil. The plugs and wires are easy to change on this vehicle and should run you no more than $50-60 for the new plugs/wires and if you know someone or you want to do it yourself there should not be that much labor involved. For my Hyundai Accent that has almost 200k I use NGK plugs and NAPA Belden Maxx spark plug wires. This is the most likely cause of your continued problem. Hope this helps

Check the spark on cylindre 1 if its ok. that means your first cylindre timing valve or adjuster are not good.

Try spraying some brake clean where intake manifold meets cylinder head and see if engine rpm changes if so chances are the intake gasket is leaking.
