I have a 1998 car with 135 thousand miles on it it is suppose to go 0-60 in 9.9sec but it will only do it in 14 and it has some upgrades like a kn cold-air intake so is there anything I can run threw it like sea foam to help restore the engines horsepower
No additive can restore the wear caused by high mileage and jack rabbit starts to time 0-60 acceleration or 1/4 mile times.
no additive will replace rings and valves,,,UNDERSTAND? guess not
It has 135 000 miles of wear, the engine is bug gerred.
