Help i have no idea what to do...

just now about 10 minutes ago i was driveing along... then i lose all this power and my engine starts misfiring BAD ... i pull off... shut the car off and pull up the autotap.. re-start... it fires up perfectly... runs fine for about 15 seconds... and then starts shaking... misfireing etc.

my bank 2 o2 is at 1107mm and doesnt move
my bank 2 short trim is at -40%

i have no idea if an injector is stuck open ( 30# svo's)
or my o2 is shot...

 

Switch injector banks around, and see if the issue happens on the opposite side of the engine. If it does, it's an injector. If not, it's the O2. O2 will generally throw a code as well.

Or, hell, you can do the opposite. Swap the O2's between sides and see if the problem follows the O2s. Whichever is easier for you.

Dope

 

blinking ses but no readable code... but my strims hit -43.1% then the car hardly runs... but when the strim goes back to 0 it wakes right back up and runs fine... but then it starts cutting fuel and runs like crap

 

o2's where shot... runs perfect now

Were your O2s coated? What kind of fuel do you use?
