Hey Scotty long time no speak how you been? Anywho I've noticed that with ny mustang when I start it up and go for a ride in it it won't accelerate past 30 mph but after I press down on the gas for a while it'll start to go faster and act as if nothing was wrong in the first place already checked my spark plugs changed my oil.. any ideas as to what could be wrong?

I now clogged catalytic converters can act like this have you checked that, i'm sure scotty will get to your question, but it's a place to start.

I haven't checked that yet 🤔🤔🤔
