04 suzuki forenza problem again!!! I miss firing and the obd II code is p2610
ECM/PCM Internal Engine Off Timer Performance!! what is this ever since this has happend my car will show its over heating so i shut it off and then i'll turn the car back on after 2 min. its back to normal then up again!

 

Coil could be putting out low spark. Crank position sensor would cause a misfire. Dirty fuel injectors would register as a misfire. (fuel not vaporized properly would not ignite) Anyway not really sure but try checking those parts. I hope you fix it soon.
