...spark plugs, water pump? i have a 1995 toyota corolla, had to get an engine put in it because the oil dried out and I locked the engine trying to turn it back on. My mechanic found an engine with 72000 miles on it (a junkyard one where he buys often) and the day I got my car back I drove it home and was fine and I drove it a few hours later and my check engine light came on. He put new spark plugs, water pump, the engine etc. all I needed to get the car good. Is it safe to drive my car again tomorrow? Tomorrow's sunday and he's not open until monday and I need it. Thank you!
