Thank you guys! I was a bit worried, because I read another thread somewhat related to this. On that thread, he ended up having to change some valves or something (I'm still a noob at car stuff, so I don't even know what it is. HAHAHA). But Praise God that nothing's wrong with our cars.
I bought mine used too, so I don't know how hard the previous owner drove it. There were mods, but I'm praying for the Best! Hopefully it will last me another 6 years. Enough to save up for an engine rebuild.
