Any help would be greatly appreciated! I have a 1998 Suburban - the other day I was doing normal driving and started smelling a burning smell - this was *not* an oil burning smell! I swear! I know what oil burning smells like! (Sorry, just frustrated) This quite seriously smelled like a grass fire. In fact, until later I thought it was a grass fire in the area I was driving through. As I got into town the check engine light came on with a very sudden rough (very rough!) idle at the stop light (significant misfire - extremely rough). Thought it was going to die so I carefully drove to where I was meeting someone, turned it off, let it cool, restarted to see if it would do the same thing. Yep. Managed to make it home, opened the hood and smelled the fire smell from earlier - but not as strong, like an old campfire. Mechanic friend suggested starting with the spark plugs and wires because the plugs were really fouled and the codes were saying missfire on 2 and 8. Did that today. Smell has faded. Missfire continues. Any ideas?
