Hi I was hoping to get some help with the 22re in the 1985 4runner I picked up recently. Thanks for any insight.
O2 sensor?Valve lash?compression checkpull plugsremove FI fusepull coil wiretie open throttlecrank until needle stops - 3 - 5 seconds.Gnarls.
Before pulling the injectors, replace the O2 with a plug and play one, not a cut and splice one.Did you check the intake tube for cracks, the accordion section will develop cracks with age, causing unmetered air to cause the O2 to richen the system?When you tested the sensors, where did they test in the factory acceptable range? IME, I have found that when a sensor is testing near the ends of its acceptable range, and you can find no other cause of the issues, the sensor is the cause of the issue, and has just not yet failed outright.
Ok your tps needs to be set as such.Idl - e1 continuity while blade closed.Idl-e1 goes open as soon as you crack the blade.
qmikep... did you do a compression check yet?Gnarls.
Grounds? Vacuum leak? Old vac lines can surprise you. plastic nipples on Vacuum control devices can easily crack or break when jostled around causing leaks. Greasy/oily grounds can cause continuity issues or even help bolts vibrate loose. Check your ignition wires for leakage. In the dark, look for arcs between the wires and any grounds, or do it the hard way and lean against the vehicle, being sure to have a good ground to your body, and run your hands along the wires. When you get a shock you've found the leak( very bad suggestion, added for comedic relief). You can isolate the ignition wires from each other and any grounds to see if that alleviates the misfire. Check distributor cap for carbon tracking. Just a few thing that commonly show up after being moved around.
