Engine Sound Help Needed
Last week I had my RMS replaced as well as two gasket seals at the Jeep dealer, as my local won't do RMS's. Less than 50 miles since on original engine with 93k. Today I fill up and I'm driving and the engine starts to make a sound like it is ready take off or explode. it is a solid continuous booming sound like you are at a steady high RPM. The tach needle did not rise, the oil needle did not rise, the temperature did not rise and no engine code. It happened twice now and lasts 30 seconds to 1 minute. I can't see anything banging with the hood up and it is definitely coming from the engine. Could this just be bad gas? I can't see taking it back until there is something for them to confirm, like a light or if it does it all the time. Any ideas?
