Re: newb here... got some issues
done... figured it out.. was plugs initially. changed the wires also but i grew up w/ gm engines where one bank had 1, 3, 5, 7, and the other was 2, 4, 6, 8. my brother changed the 2 plugs i told him but what i thought was cyl 4 and 7 like my scanner told me, he actually changed 4 and 6. we eventually changed all plugs, and wires, and got a look at an alldata printout telling me i had the wires mixed up. at one point, we were running on cyl's 1 and 8 ONLY!! my dads hyundai was lookin good then! everything is back to good now tho. it's a 5.0 finally. kinda tired feelin, what's the best place to start w/ some mods?? are exhausts simple for these?? i see the stock muffler is a dual inlet muffler.. prob be a PITA to run duals on. what are some decent "bank for the buck" mods for the 5.0?
