If anyone has a technical information regarding a 4AF engine, AE92 model, please can somebody share it? I lost my owners manual so I'm in the dark on the tech details of my engine.

What sort of tech info are you looking for?

4AF engine info like what is specified in the owners manual. Plug gaps, sparkplug specs, settings, etc. Any info will do, thanks in advance.

I set my plugs to 1mm gap, ran the timing up to where the engine would ping a bit , then back it off a little.
You should be able and get most of the info from here, or elsewhere on the web, most everything is the same as the 4afe.

the 4A-F it's a 1.6L engine with 90hp. It's low in the hp, but no spend much gas. The problem with this engine is will not have a ny supercharged or turbo kit for this car. Exist many form to have more hp, for example, put a header (the header os 4A-F & 4A-GE not is the same), change the oxy sensor, chage the type of air filter, or put a mod chip.
