Having problems with your 1991 Toyota 4Runner ?
I have a 95 4runner 3.0 ltr I had code 52 which i know is the knock sensor I since have replaced the sensor and the harness. It idles good but hesitates under throttle and i still get code 52. Is disconnecting the battery enough to erase the code ? i have pulled the fuse as well.
