I have an automatic 1998 Ford Excort ZX2 2.0 DOHC with 198K miles. I was driving my car back from the airport after it had set for a couple of days and it was about 10 degrees F out. I noticed that I was not getting heat and though it might be my heater core. I did not see where it had leaked in my floor board and I did not have any pools of coolant under my car or dripping from it as I was driving. I started loosing power as I went up a hill and started to hear what I though might be my waterpump making some noise but I was not loosing any water that I could see. It continuted to drive until the next hill where it lost power again and died. After it died my service engine light came on, but no warning lights prior to this. Long story short I hauled it home, and reset the timing and it would turn over by not start. I have fire to each plug and I drained the oil and it smells burn but does not look bad. What should I do next? I think I will fill it back up with oil and do a compression check. Any other suggestions?
