ever change the fuel filter? check engine light on ?

[98StangGT]

No I have not changed the fuel filter, and yes the check engine light is on, but I thought it was on because I have no cats on it

^^^Very much so. if the CEL came on after you went catless, this is the problem(and no big deal)

does the car feel sluggish(well, for a npi) when the exhaust tone starts to break up in the higher rpm?

Do u think seafoam will help at all?

Get a set of MIL eliminators (hopefully your pipe still has O2 sensors) and then reset the computer by disconnecting the negative battery cable for 10-15 minutes. Then take it out and drive it (Normally) for about 30 minutes...all should be good then.
