Hey ya'll just picked up my first LJ yesterday and I'm super pumped! Haven't owned a Jeep since I was in High School (95 YJ) and I've missed it. It does have a couple issues that I'm currently fixing to include: a little play in the steering wheel, check engine light for O2 sensor and the speedometer intermittently works. I have some parts on order to hopefully resolve these. Sofar I've changed out all the fluids and spark plugs, cleaned the engine bay, undercarriage and inside. Any other recommendations for initial maintenance??
