i have been having problems with my car bucking at a high acceleration and then getting worse and worse as the car heats up and then when it was cool it would be go back to the not as bad problem. 2 days ago i tookm it skiing and on the way home it was doing it very bad and then i got home ands turned it off, a couple hours later i turned it back on and it will run very badly no power backfiring cylinder misfires cant rev past 5000 rpm will idle at 500 rpm and die constantly. when i went to the mountain right before i was about to start going up hill i stopped the car to let it cool and it was like it would not shut off it kept turning over for about 5- 10 seconds. i have checked the vacuum cleaned egr valve fuel pump dist. could it be spark plug wires or plugs? i just put new plugs in about 5 months ago also the exhaust is pouring out black stuff onto the ground from the fumes like when i put in carb cleaner just stains the ground darker? ? ? ?
