Hey there every body been a huge fan of this site for help and now on really stumped on my rig and need some help, I have an 88 4runner with a rebuilt 22r and a 4 inch on 31x10.50 , and I have a bit of a power problem, now yes I know its a 22r and a 4cyl but I feel like it should still be able to maintain 75 on flat ground/freeway and pull a hill doing at least 50, bit my problem is that 1st-3rd gear is fine and I can usually hold 60ish with 4th and haven't even touched 5th since I bought it but then when I hit any incline what so ever I'm downshifting to third and most hill all the way down to second! Any help or ideas would be amazing!
