ENGINE MISFIRING

[Lipinhu]

Quote: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.

I dont think it it is a firing problem.

I had the same in my white ae86. It was because of the battery, i had to source power from another car, and when i took off the battery cables, the symtoms were exactly the same. Check some groundings. The revmeter goes that way because of the incorrect voltage. Just my 2 cents.
