thanks for responding man ive tried a few things but nothing has worked . whats the sd?
SD=speed density. Pretty much if the pcm detects a fault with the MAF, It throws a code and goes back to running the engine with the MAP sensor. Some codes unless cleared, can be redundant. If resetting the pcm dont help, you may have to check the wiring closer, perhaps its broke in another spot besides where you repaired it. Also, if the MAF wires grounded out when they got broke, the EMI fuse may be blown.
