jim, Good to hear from you. The check engine lite is on. Pulled coded and got one for crank sensor (L-5) Car is running different, better, more power, smother idle. I thought is was from bank firing the injectors because fuel mileage seems to have taken a hit. The car is a 95 with 83,000 sensor can be had for around 50 Bucks so I feel not a bad investment. I was just wondering how tough it is to get at. I know it's at the rear of the engine but I havent had the time to really scope out its location. BTW your fan relay sure is working great here in this New jersey heat wave. Thanks Ed
