so this has been an issue since ive gotten the truck only the tach and spedo and mabey the battery light work? the fuel gauge bounces around the temp gauge sits in the blue the oil pressure gauge is stuck over to the right? but just today i was going into town and a friend passed me and he called me asking why i was driving so slow ( my spedo said i was going 65) when i get to about an indicated 68mph the little pointer thing starts jumping around. also is 4000rpm normal for a 86 2.5 4x4 in 5th gear going 55-60? one thing i do know is that my tires are not stock size...i have 235/75/15 now wich replaced 215/75s but talking to the guy i bought it from said that those wernt stock size either he just took them off his xj and put them on the mj...i got the build sheet from the door jamb and under tires it says 6374 whatever that means? mabey this shouldve been split up into multiple post idk...anything would be great
