04 gt, just replaced my belt and idle pulley, I dont know what I did, but the belt tensioner is rubbing on the timing cover, my belt routing looks good, my idle pulley looks fine, I think from pulling the tensioner and it being OEM it might just be worn, I adjusted everything and it doesn't run...

2004 gt, factory intake manifold, this bolt hole behind the throttle body towards the passenger side, goes into the plastic manifold, what's it for? Just wondering if somethings supposed to go there. (In the photo it's the hole with the brass sleeve there, between the TB spring and cable)

I come from fox bodies, so I'm new to the 4.6. I'm wondering if my 04 has the upgraded manifold? Under load on the freeway it gets a little bit of shaking like its motor mounts, but it seems solid at idle, any ideas what it could be? Heres some photos of my manifold. Thanks

Do the 4.6L and 3.8L share the same motor mounts? Would aftermarket maximum motorsports 4.6 solid motor mounts also fit 3.8L V6? Edit. The car is a 1998.

So, I did the intake manifold swap for my car. Went from a crappy Dorman intake for a non PI motor and put on the Ford Racing Performance Intake manifold. It was actually used and off of a 2002 Grand Marquis but same crap right. I now have a misfire. Yesterday she ran like a top! Now...

Hello I recently put a new clutch kit, (clutch, bearings, and pressure plate) and flywheel, I also put in a new clutch form because it was broken in my 98gt and beforehand the clutch was SUPER stiff.
