as i was removing the headers i decided to just take out the a/c lines and condenser and also the emissions and smog pump.... every now and then when i drive after about 5 -10 min my check engine light turns on and doesnt shut off untill i turn the car off n e ideas?? when i was installing the headers i did remove i belive the knock sensor on the bottom right of the 350 just under the header and found out the wire to it was melted and so was the temp one on the other side of the block, could this b the cause??
