ok, my car i bogging from 1k-3k and after that it runs fine. it bogs really hard, even if im in 5th gear at 4k rpms u can feel the car jerk and stop, jerk and stop, etc, not hard but can be felt.

its funny because all i did was change the valve cover and change my oil (syn.) and i test drove it and it stared bogging. since i never put syn. oil in it before i change my oil again to regular 5-30w, but still the same thing.

only thing i can think of it doing this is a foul spark plug or some bad injectors. anyone else have this kind of problem?

 

considering it started after a valve cover job, im gonna say check your wires and plugs, make sure that the connections are good and that the clip inside the spark plug wire is reaching the plug and not just going up inside the bood

 

Also check all vacuum hoses. Also stay away from synthetic oil unless you've used it since the motor was built. It's just a waste of money for older high mileage motors.

 

Bogging, I love that word. Last night some chick was "bogging me up".
