update on my misfire issue

[quagmires_sho]

now the car starts right up with minimal cranking, idles at ab 2k(absurd) and then over ab a minute slows down to 700 n then drops right down to 200 and once its at 200 the lights flicker and whole car (especially passenger seat) shakes quite
violently, the light flickering and high idle are new. before itd barely start n go straight down to 2-300rpm. another note is if i blip the throttle before it dies it stays at 1k for longer.

You don't want the idle to get down that low. The oil pump is mechanical and needs more rps to pump enough oil.

What did you do between how it runs now and how it ran before? Did you mess with the idle screw?

i didn’t mess with the idle screw but i undid the secondary vacuum line again, i believe its an ignition issue cuz it clearly is getting the fuel and air its j the spark that falls off, i can tell its getting fuel cuz all the unburnt fuel is quite pungent, n it was getting plenty of air beefore this issue came up, but the ignition module seemed to be going bad before.

also about the oil issue, should i just cut the engine off before it goes too low? also is there a wideband afr gauge i could get thats kinda plug n play? the lean/rich issues this car has makes me paranoid

I'll have to look for wideband but you either keep enough throttle to up the rpms or don't let it run. too much low oil pressure over time is a problem. The bearings can't take it.

With engine control issues such as these, your first step should ALWAYS be to check for codes, even if the CEL didn't come on. Very few codes throw it:

EEC Self Test Procedure - V6SHO
