Hi Jaxer. I have sent you messages on YouTube as well. Appreciate your content. I notice that when my jeep is idling in the garage it is leaving or throwing out of the tailpipe black soot on the concrete. The jeep is running fine to me, but I am sure this being left on the ground means I have something that needs to be addressed. It is not throwing any lean or rich codes. It idles smooth. It starts right up. It is not smoking. Could this be a fuel injector issue? It has new plugs. The jeep has 192k miles on it and the sales pitch from the only owner of the vehicle is that it was Pulled\/towed a ton allegedly but I believe it has been driven a lot as well. Thanks for your thoughts.

Hey Don, <\/p>\n\n\n\n
My initial thought is you tend to let it warm up in the same spot often. Park in the same spot, and it sets for long periods of time allowing condensation to build. The converters on these engines work hard and in doing so spit quite a bit of moisture out the tail pipe in addition. <\/p>\n\n\n\n
It\u2019s just condensation from the exhaust system heating up, and it will sometimes blow that mixture of condensation and carbon out of the tail pipe when the engine is warming! You don’t need to let it warm up before you drive it. Start and go! When that check engine light comes on, then we can start to worry. <\/p>\n\n\n\n
Sounds like you got yourself a nice one! <\/p>\n\n\n\n<\/a><\/figure>\n\n\n\n\n<\/div>4.0 GPM Pressure Washer by Simpson - Assembly Tips and Review * #mechaniclife #contractor<\/div><\/div>
