I bought a one owner 92 YJ 4.0L HT with 215 000 kms on it. The check engine light was on, and the guy said it had been on since 70 000 kms. The only thing that buddy had done to this Jeep was replace some belts and hoses. Nothing else other than the basic stuff. Never had taken it into the dealer after he purchased it and from what eye saw it was used alot but the body was still in good shape. I sold it with the light on, and the Jeep still had not seen the dealer since 1992. This was in 2004. You hear of all those mysterious things that happen after the Jeep hits the Stealer. Crooks is what they are, they should be charged. I think Jeeps reliability history is bad 1. because the abuse they see [ crazy ] and crooked dealers [ Jeeps are so easy to screw around with ]. It makes you wonder.
Oh yeah, buddy never even changed the fuel pump or filter. Jeep had tons of power but the valves were going, making it sould like a diesel.
