LOW ENGINE PERFORMANCE

2001 Toyota Corona

Engine Performance problem
2001 Toyota Corona 4 cyl Two Wheel Drive Automatic 99120 miles

Sometime this year, a local mechanic opened up the cylinder head of my car to replace worn out valve seals. Since then my car does not generate enough power up a steep hill especially when the engine has become hot. Sometimes the engine becomes very hot after accelerating very fast over long distances. What could be wrong?
