ok so not too long ago i had a huge overheating issue and was running on no coolant for a couple miles. burnt up my coolant sensor and needed a new radiator. all replaced. Now i when i accelerate i lost the deep tone i had with my engine/ exhaust manifold/ flowmaster exhaust. so its like a high pitched whining noise when i accelerate or press on the throttle. if its my intake manifolds what could actually be wrong so i know what to look for?
