have you checked your timing?

**94gt5.0** · 02-21-2010, 10:37 PM

no i havent it was running fine before the install no shake what so ever

well if its running fine, maybe you have a clearance issue and your headers are hitting the body somewhere and thats what you feeling?

Does it idle like crap?

no it idles ok when you start to move it has a shake too it and when you sit still you can feel it shake as well but it seems to run fine

It would idle like junk if the firing order was off. What all did you remove when putting them in?

if it feels like it's dramatically slower at WOT then you probably mixed up the firing order. I did that when I installed mine and it took me a day to trace it to the firing order.

no just the air box and smog tubes just what i had to to get the headers on

I bet you may have cracked a spark plug if you didn't remove them when installing the headers.

Id start by replacing the plugs. If you droped one it may have damaged it.
