I'm Awesome
Hi all - 1998 K2500 5.7L 249,000miles. So this is where I'm at. I have mechanic notes stating that the intake manifold gasket needs to be replaced, and I am planning to do that very soon, and have the parts. In the meantime, I knew I was having some coolant leakage issues, so I replaced the radiator, hoses, water pump, thermostat, and coolant temp sensor. I was also having a bit of a rough idle immediately prior to that, so I replaced the plugs as well, see pic below for the worst looking ones when they came out. At this point, about the only thing left to do is the intake manifold gasket, but what I'm smelling is that I'm running rich somehow, I can smell gas. Would a bad intake manifold gasket cause this, and what would be the best way to look at the mixture settings or whatever would be causing me to run rich? Thanks, I have a code reader I got from a friend, and the auto parts store is close, and they will read them as well. Appreciate any thoughts you may have. The rough idle seems to have smoothed out, but it is still there subtly.
