Various issues with '97 Crown Vic
I have a '97 C.V. with a few things going on, and was wondering if anyone has run across any of these before and has successfully resolved them. It is a 4.6l, non-interceptor, auto tranny. Right now, I've just failed the Illinois Emmissions test only because of 0171 and 0174 codes (lean on banks a+b). Under hard acceleration, the car accerates live a GEO Metro....no power at all. If I give it 50% throttle, it actually moves faster. In the winter, she won't run on her own for a good 5 minutes. If the heater (blower motor) is on, she surges from about 800rpm to about 1200rpm every 5 seconds. I don't know if these are all related, or seperate issues. I was standing in back of a guy at a parts store today, and he had a Grand Marquis with the same code and lack of power. I didn't get a chance to talk to him, but it sounds like this may be a common thing. Any help would be great. I want to get her running good.....there is nothing like driving a big car on the highway.
