out of ideas.

Car: 1998 Formula

Miles:130k+

Problem: random miss on #5 Cyl.

Stuff Ive already done to try and fix/track down the problem: Changed the plugs, wires, coil pack. Swapped #5 Coil Pack with #3 to see if it might have been a bad/new coil pack, Swapped injectors to see if it might have been the #5 injector going bad.

Stuff I havent done yet: Was told by a friend the other day to do a compression check.

Everytime I stick the computer to it its always on #5 Cyl. Im fresh outta ideas other than pulling the motor and just redoing everything...

Possibly a valve going bad?? Whats yalls take on this?

What does the number 5 plug look like, do you feel this misfire or is throwing the code only?

the next thing i would do is to pop the valve covers off and have a look at the valve springs

as elias stated i would pop off the valve cover i have seen where the rocker arm bolt has been pulled out completely,treads and all(loves aluminum). if everything turns out normal there i would do a compression test,may have a burnt valve.
