Happy new year, everyone!
Last Monday(12/24) night I was driving my roommate to IAD with a real high speed... As we were approaching the airport (5 mins left), the EPC light went on for around 10 seconds and simultaneously, I felt the car lost some power but it recovered after EPC went off. At this time MIL was still off.
After arriving the airport, I turned the car off and waited for 20 mins and then I drove back home. About 5 mins after I left the airport, MIL went on, but (as I remember) EPC was off. I then stopped for a while, and have no choice but keep going on. Everything was fine during the trip back home. (Only MIL was on all the time.)
Later I learned from this forum (thanks guys
) and bought a VAG-COM. It got two codes:
My bug is 2001 2.0L Gas with 95k on it.
I've searched around for the Engine Speed Sensor problem, but answers seem to have a wide coverage... for the problem related to cooling system, I don't know whether it's a new or old problem... back 5 month ago I didn't notice the coolant level until the coolant light turn red
(I added the coolant immediately after that)
Another supplementary is that, in March this year, the EPC light had been on for several minutes when I was starting a trip on an interstate. I stopped the car, turned it off, and then restarted, EPC didn't show up again, and it didn't trigger MIL. Everything went smooth, until this Christmas IAD trip.
Thanks for help

UPDATES:
- Thermostat was bad (early open; soft failure), replaced in Jan 2013.
- Started to have P0118 [Engine Coolant Temp Sensor (G62): Signal too High, Intermittent] since Feb 2013. Changed the old black coolant temp sensor to the new green sensor in June 2013.
