At first blush i would say water in the gas... buy a couple bottles of gas line antifreeze. put them in the tank and let it set overnite if you can tho sometimes it works faster then that. gas line antifreeze is alcohol (NOT the kind you would drink).
if that solution doesn't work the next alternative is that the coil pack is going.

SOUNDS LIKE A BAD SPEEDOMETER if you can use an OBDII while driving and look for DTC output from speed sensor. possible loose connection can cause this as well

My 2003 ford explorer bucks when going down the road - but only with snow or rain present. Sometimes, it bucks hard with a hard braking feeling...Sometimes softer like an engine miss from bad spark plug or...


well you should do a diagnostic code check. although a code read will not show things like , bad air filter causing motor to mis fire, it will not detect a bad intake gasket, it will not detect a bind or bad chain gear in trans or axles. but it will give you a better understanding with the motor condition and then you can start eliminating causes till you get to the problem. I wish the best to you

I have a thomping sound on front pasingers side i did think it was the exsaust box but that is ok


is this during acceleration or while hitting bumps? If it is during acel, then its prbably an exhaust leak (don't know what you mean by exhaust box) but a leak can be a gasket or rust hole. if it is when you hit a bump, it could be some system loose or shock/strut mount

The clock on my Nissan Pathfinder is acting funny. It goes on and off during normal driving. If I tap on it, it lights up. Help!


That is a typical problem with many late model import vehicles. The observations that the clock goes on and off sporadically and that tapping on it turns it on leads me to believe that the clock is going bad internally. I offer a very reasonable repair service for many late model imports. Check out www.autoclockrepair.com
