wassup guys I have a 2005 3v and it runs great I have a sct tune basani x pipe flowmasters and cold air intake and the car ran really good for a long time but now it’s like when I get speed up to 100 it’s a bad miss I thought it needed a tune up so I bought all new msd coils and a set of motorcraft spark plugs and that still didn’t fix the problem and it has lost a lot of power I heard a rattle one day and it sounded like something came out of the exhaust pipe but I didn’t see anything when I got out and checked but it has lost a lot of power since then and I heard some ticking also which sounded like a lifter so I was going to buy all new lifters and rocker arms I wanna do some upgrades but I wanna fix the problem first but I can’t figure out what it is and it has 109k on the mileages
