well i took my truck to a shop to set my timing and they put a timing light on it but never put the number one piston at top dead center.should they put the piston at top dead center before they put a timing light on it. when i drive it it seems to me it is missing real bad but when i get up to about 60 or 70 it drives alright but it still misses a little bit[/quote:e55b6a1652]

There is no need to bring #1 to TDC if your checking the timing with a light. It will flash everytime the cyl. fires.

As for the firing order, its....1-8-4-3-6-5-7-2

ok my truck seems to be in time but it is still missing real bad. i have new plugs and wires what can be wroung now
