I have a 2003 Crown Vic P71 Runs really smoth in first and second gear but bucks badly in 3rd. If I kick it into passing gear or let it drop back to second, It's smooth again. I do not have a code reader and am not , by any means, a machanic. Would some know if it is an engine or a transmission problem? I would hate to take it to have the tranny rebuilt just to find out that it was an engine problem or visa versa. Any help would be appriciated.

Ha! Love the sticker in the back window. I too have a 2003 and though I don't have this problem is sounds suspiciously like a tranny problem. Sounds like it's jumping from 2nd to 4th or doing some screwey overdrive thing.

I too am no mechanic and you'll probably get better responses from others but it sounds like tranny to me.

It sounds like you have a bad ignition coil.

If you are getting a CEL (Check Engine Light), you can go to Autozone or O'Reilly's or Advanced Auto and they will pull the codes for you at no cost. If no CEL, then I would look for a reputable mechanic to look at my car.
