sounds like the same problem i had after sinking mine. code 52...knock sensor? did you try and disconnect your tps sensor and see if it runs any different?
Is there any heavier duty coil springs that can be put in the rear. Tryin to use used springs off another truck, ya know the whole budget thing. Wanna get rid of that sag in the rear.
Is there anyone who has dropped a straight 6 in a 4Runner? I'm sure it has been done! I am wondering if its possible to drop one in out of a land cruiser or a Supra. And if anyone knows the best way to do it. Thank you!
