Heres the low down. I was driving and got on it, hit 10 psi of boost like it always did, then car just shut down. It barely restarted and i could make it home, but couldnt hit boost at all or would stall. On way home first couldnt go over 3k rpm, then by the time i got home wouldnt go over 2k rpm. Now car starts and jumps around alot and actually idles in boost to stay running, then stalls out.
No codes were thrown and i thought fuel pump crapped out, put a new w body high flow and still same symptoms.
Any help or ideas?
And i also rulled out coil packs, plugs, idi cover, i swapped all that from working car so its not that either, im at witz end
Yup all are good, will double check again. Did a compression test was 212 across the board ( is that normal for ld9 )The while plugs were out looked at them and there really black, but only had 40 miles on them? What would cause that?
What were/is your air fuel ratio at? Check injectors maybe
No idea on a/f ratio, its just gm tune so probably rich, will check injectors
No intake gasket leaks? Cel?
Found out what it was. Cat was so clogged it melted the front o2 sensor!
