Sputtering issue under load at lower rpm's.

[Cobraonr]

86k miles on 98 Cobra. Original owner. Ever since she was new I recall this situation so I wrote it off as dumb shit, just down shift.

Is this expected, or should I go after plugs or wires?

Been running this setup for 5 yrs now.

IMRC delete, LT headers, o/r X, JLT CAI.

SCT iTSX 93 tune.

Pull plugs and read them.

Take off wires and OHM spec them. Wires can physically look good from the exterior, but the internal core does break down…
