Got a misfire..alot of misfiring..
Lets start. 99 5.4 with 265,***
Just started running like hell about a week after i ran seafoam. Used it before and never had a problem. Im just noting that.
Codes kicking but not all at the same time. I cleared codes and drove it and got more "new codes"

I have no air leaks, i know what and where to check. All good.
EGR cleaned, but not tested.
Tps is fine, checked
Dpfe not sure how to check that.
I have replaced all plugs and injectors and two coils. Still having a misfire on new coils.
Cleaned MAF.
Compression check was done on cylinders 1 to 4. Thats the only side im getting the misfire. If it was a EGR, MAF or a air leak i believe the misfire should be on both sides.
Compression check ranged a 10 to 12 psi difference from cylinder 1 to 4.
What else and where else to check??? Im lost!
