inconsistent spark Options

Hello everyone, i joined just to comment on this problem.

First, let me express my sympathy to anyone who suffers from this problem. Feel free to contact me when you prepare to scrap your car so i can attempt to talk you off the ledge.

A bit of background. I run an electronics specialty shop in Norfolk Virginia and i recently got a celica in my bay with the same symptoms. I have over 56 hours in this car between shop and after hours research. I stopped charging the kid hours ago because it is now a personal matter between me and this car.

Please do not rush out and buy anything. make any changes to the timing.

do this first.


take off the distributor cap and remove the rotor and dust cover.

using a flashlight take a look at the condenser buried in the dizzy. if it is in anyway looking like the sealing on the front of it is bubbled and burnt. remove it and replace it. also, look around for a new ECU, don't buy it just find it.

here is why this is important. the condenser is just a capacitor that absorbs and earths "Counter electromotive force". ( Forward electromotive force is what creates your spark across the spark plug.) counter electromotive sparks can only go 2 places. into the chassis ground or it seeks out and destroys the B+, Batt, or Sensor E12 circuit of the ECM.

i have to go to the store but i will post when i get back.
