my RB20 won't stay idling sometimes if it starts to lean out.. Do you have a wideband?

[RB25GUY]

yes i do when it does stay on for a couple secs afr is normal 13.7 ish then starts dying out and goes lean to where it wont read anything.... this is what the commander was reading when i managed to blimp the throttle a bit and it was hard work trying to keep it from dying

Looks like your timing might be way off.. Why would you be getting 5 counts of knock at 2k rpm just blipping the throttle

Also I don't know how these engines are, but Timing usually is 45-50* when in cruise, and like 12-15* at idle ( at least that's what my mazda always ran )

[RB25GUY]

i mean before this it ran fine and at idle when its was good it was like 15-20 degrees most at idle mine never goes above 45 degrees but like i said every time i tried to hit the throttle again it would die out

Maybe maf is messed up and Giving false readings. My maf will cut fuel completely if it goes above 4.7 volts. and if the maf is giving crazy voltage it could happen.

What size injectors are you running? You double checked to make sure all your couplers are still in place right? It almost sounds like one of them completely off. I'd double check that and make sure one of them didnt accidentally pop off and just kinda sitting there but not really attached.

Then I'd check the tune on the PFC and make sure it didnt dump your settings, specially injector/MAF settings. Start with those...

Then do the usual check...spark, gas, compression test.

as far as i know the injectors are 550 with a 255 walboro and i checked it and nothing erased on the PFC the maf settings, the fuel pump settings all of it is on point....i do remember the lights in the cabin flickering a lot do u guys thing my alternator would do the same and not keep everything on? i will check the spark plugs, i know its getting gass bc i hear it prime everytime i start it as far as the compression test will be done tom.......

so we came to the conclusion that it was my CAS
