Well almost guys, when I start the engine, it idles fine for approx 5 minutes (more or less), then suddenly it wants to stall, rpm drop to 500 but then rise to 800 and it idles fine again.
When driving, it runs fine again, except for when changing gears up and pressing gas pedal - feels like engine is braking for a second, accelerates with a delay and it doesn't matter if I floor it or just press it like on sunday drive.
IACV and throtle body cleaned twice - made no difference.
EML not on, only fault codes stored are 0130 and 0560 due to poor battery that was replaced three days ago.
Oil changed every 7000km, filter too, air filter clean as new, spark plugs done 5000 km.
I'm buffled, really guys :-\

Sorry I forgot to say that unresponsive acceleration starts when engine warms up. It's ok when engine is cold

Could that be the difference between open loop and closed loop ?? When cold its in open loop and runs fine, warms up, goes to closed loop and mucks about ... so, what are the fuel trims doing ?? Can you get any live data off it ??

No, and I don't know how would I do that :-X Are you suggesting an O2 sensor could be faulty?

Just one more question guys, would an O2 sensor from a donor veccy with X20XEV engine fit into mine miggy?
Thanks in advance, Stan
