ENGINE MISFIRING

[Onyx]

Hi guys,

I need your help, or valuable advice.

My engine doesn`t run well and after last reparation it didn`t change at all. One guy, who knows a lot about AE86 is helping me, but doesn`t really know, how to find the routecause of it.

To take it from the beginning.

1) when i start the engine, it runs fine. 1000 rpm isn`t a problem.

2) when it gets warmer and I push the throttle to go slowly higher and higher, when it goes above 2500 rpm, the rpm-meter goes crazy and counter goes up to 7000 or even higher. Real revs of engine are of course still around 2500-3000. Then engine diagnosis controls is on and the engine swithes off. When I keep on revving it, I can allow it to do not let it die, but after a while, the engine turns off anyway. This is how it looks from inside.

3) From the outside it is different story. 1000 rpm is of course still fine, but when I go higher, whole engine starts to shake and do weird noises, like ticking. Timing of these ticks isn`t consistent. Sometimes it is more, sometimes it is less. Location of this noise seems to come from the bottom of TVIS injection manifold.

4) false codes: 3, 6 and 10 if I remember correctly. Even if we take out the fuse of ECU, after plugging it back in, false codes are still in.

I have changed sparks and cables. Yesterday I swapped also distributor with different one, which normally works in another car, but nothing helped.

I have also driven car with these conditions for about 300 kilometers, with consistent shaking like sh*t, engine sometimes turns off by itself.

And this was coming step by step. Car wasn`t running for 6 months and for first two days after pick up it was running perfectly. Then there was one tick in one hour, then two, then 10 and then it end up like this.

Whatever you have in your mind, please let me know.

THANKS FOR YOUR SUPPORT FELLAS!

PS: If you want to hear the noise, I can make short video and place it on youtube. Let me know.
