*IF* the problem is the injectors, fuel system cleaner may take a while to do its thing, & if it hasn't been used regularly, may not help, or may take 2 bottles. (Techron is one of the best, IMHO.) It also might cause some stumbling, etc., while it is working, so that could complicate things.
As I mentioned in the other thread, after pulling the fuse, my engine dies in about 2 seconds. I don't relieve the pressure at the fuel cap until *after* I run it & let it die - did you do it before? Maybe for some reason that would make it run longer????
I also am able to fill a large jar about half full when I pull the lines off, so I think it's normal to have a lot of gas run out.
I don't know much about the Apexi S-AFC, & just the fact that you have one means that you probably know more about many things than I do, LOL, but maybe it *is*, as you suggested, misbehaving & causing problems???
Do you know if you're running too rich?
I'm assuming no engine codes?
I wouldn't rule out the wires or coil pack even though you mentioned experiencing some surging - intermittent failure of ignition components can cause a computerized engine to do some strange things. FWIW, when I had a wire go bad, no codes were thrown until it failed completely...then the engine wouldn't even start. Are your wires due for a change? Are they original? I would want to replace them at 42K if they are - this engine tends to kill wires w/heat. I've seen wires so often be the cause of stumbling (misfiring) problems. Just checking them might not be telling you everything.
Do you have an Advance near you? Some of the stores have new (off vehicle) coil pack testing equipment (free!!) - we should be getting ours any day now - can't wait - will be such a big help.
I would change wires before (or whenever replacing) a coil pack, as a bad wire can damage a coil pack.
Just my 2 cents....
Keep us posted!
