I'm glad to be here to help. I just I hope we can get to the bottom of this problem. You mentioned the coolant was empty. When I asked if there was any contamination in the oil, I meant that sometimes the coolant can leak into the oil if there is a bad head gasket. What you end up with is a light brown or white sludge around the oil cap and on the oil dipstick. Let me know if you noticed anything like that. Also, have you noticed any white smoke coming from the exhaust? Something other that I was thinking about was a possible plugged catalytic converter. When the engine is hot and you have driven it, check the exhaust system to see if the converter is red hot. Also, see if there is a good bit of back pressure coming from the exhaust.
Let me know what you find.
This may take a few posts back and forth. Without a check engine light on, it becomes a guessing game and requires different things be checked. I'll do my best.
