I have a problem that no one seems to know the answer to....

Everytime i drive my car..no matter whether it is cold or hot it does a really weird bucking thing. If i have it in 1st geer and i try to go with my foot all the way to the floor it seems like it is going to stall and then picks up suddenly. It does through 2nd and 3rd geer as well. My boyfriend did a code check on it and it said that the EGR valve and sensor were bad so we replaced them and the problem is still there. They replaced the fuel filter and all that so they are just as stumped as I am. Please Help!!!<img border="0" src= smileys/smiley5.gif>

 

how old is the car, maybe it needs new wire or plugs.

 

its a 90...the plugs actually just got replaced about a month ago....we tried that....thanks though

 

Did you check them? Looking at the plugs can tell you a fair amount about what's wrong inside.

 

they were replaced again plugs wires cap and rotor...and everything is normal

 

You might want to check out your fuel injectors, they could be clogged or even worse, shot. Try some fuel system cleaner from BG-44. If that doesn't help try the injectors. It might be in the fuel system somewhere...
