MODS: Can this be placed in the 2.3/2.5 section?

When you say it will not idle does it stall out? Does it hunt (constantly change rpm up and down)? Can you tell what the injectors are fouled with? Are they black? Grey? Oily? have you tried to pull codes?

i did change the oil twice cause it was so bad and the injectors i pulled out were a little oily so i changed them i pulled the fuel rail off and to me plenty of gas came out of them i did pull codes and o2 sensor bank 1 sensor 1 i changed it and erased the code it has not came up again
It does stall out will run maybe 5 seconds the rpms run up to about 1500 rpm and then starts declining immeditly to zero every now and then it will get to 500 rpm and try to go back up but doesnt just stalls out
I did change the IAC yesterday nothing changed
