HI, and HELP!! I have been driving my 83MD QV for about three months and have noticed that the engine warm-up light will not go out. The car seems to be running fine otherwise (aside from a leak in the low-pressure AC hose, which I am getting around to repairing). Recently I had her out for a nice 2 hour drive (longest to date) and the light still stayed on: during the segments when I was pushing the car a little bit the engine temp would hover at the 220's mark but would soon drop back to the usual 200's as I slow down to usual cruising speeds. What common things could I check to resolve this problem(?) ?
