Lose of horse power after having exaust manifold leak

\015 I had a squeal coming from the exaust manifold, drove for a week like that and suddenly lost horse power and acceleration. i fixed the leak in the manifold which was four loose bolts, two of them were the wrong size bolts that were installed by a previous owner. i still have no horse power. the trailblazer acts like it is bogging down when i try to accelerate\015 Posted / edited by AnonymousUser on : 29-11-2021
