When I accelerate my mustang, the potency "gets stuck", something like speed limiter. If I keep pushing the gas pedal the mustang can't accelerate more but if release it I get a little of acceleration like if it was delayed.
The heat is maybe a little more than it should but it's fine.
I recently changed spark plugs, battery, oil filter, gas filter and air filter.
What I think it may cause that is the exhaust system as everything is factory and sounds accurate to the problem.
