BOLTS

whats up yota tech ive been reading all over this site last day or two to help me solve my problem.(nice site i might add)i have a 92 4runner ,at 4x4,3vze. i got it for a good price $125.00. f/p pump bad and someone ripped off the cat, replaced both drove for a day.it ran ruff and i got code 52, so i replaced the sensor and wire harness, the p/o had soldered the wire to the k.sensor and if i touched it the solder joint would move,did a timing belt job to while i was there.well she ran fine until i got in the upper rpms code 52 again, all wires checked out ,???. while i drove it home from my boys house where we did the work she cut off on me.now no spark and my cel wont come on under code checking or with the ignition on not running.coil good, igniter good only thing i could think of is mass air flow or bad ecu? any thoughts, advice would be helpful thanks

my bad blue for "foul langauge". i also should mention the cat has been replaced and timing is dead on and was still intact after she cut off on me, compression good across all cylinders, i also seemed to find that in most of the threads with a reoccuing code 52 that no one really has posted a remedy to there problem, i guess they never fiqured it out.

My guess is a short in your wiring harness between the ECU and the new pigtail you replaced. You're right; no one has figured this problem out yet!
