Sounds like the threads for the spark plug hole on that cylinder are stripped. This is causing the cylinder to lose compression and not fire. If it can't be repaired with a Helicoil Kit you need to replace the head. Jim
Going to do a compression test on that cylinder would that make the oil smell like gas exhaust leak on the lead would that cause any wrong codes by the OBS
It could make the oil smell like gas because the cylinder isn't firing so the gas is not being burned like it should. A cylinder not firing will also set a trouble code in the computer and make the check engine light come on or possibly flash. Hope that helps! Jim
I did put helicoil in it should I try to put another one in it if so can I get the old one out it could be in wrong some how tks for advice
When I drive the truck and stop it idles like it wants to die I try not to drive .
Talk to your local auto repair shop about this. Or maybe you have a machine shop nearby. Unfortunately if the Helicoil doesn't work, the head will need to be replaced. There's really no way around it. Jim
