Okay so I got vacuum tester I’ll show pics of idle and gauge but I noticed when I held it at 2k RPMs I have a slight misfire I’m assuming possibly bad plugs? At 2k rpm’s it stays steady at about 23 on vac tester. Maybe not plugs but something else I’m assuming with good vacuum I have good timing but that misfire is causing my loss of power issue.

Also let it run for a while then decided to try to pull codes while running. while running got code 41 and then after running I did koeo test motor was definetly at operating temp it gave me codes 21 and 82. now I have a 1988ranger 2.9 and it’s a 4x4 5speed so I’m not sure what 82 code is for but 21 is ECT sensor now will that cause the loss of power and lean issue? Will note that starts hard except when it’s been running for a while and the fan never kicks off.
