I have a 1994 Sidekick, 4 door, 16 valve, manual tranny, 4WD, 125000km.
According to the previous owner, the car sat alot before selling.... It bucks when you give it gas. It does it less so when the engine is warmed up, but is still does it. I unplug the MAF and it runs better, but this might be just because of the open-loop state of it.
I have checked the spark plugs, adjusted the gaps on them. The air filtre is clean, I have yet to change the fuel filtre.... but can these things really affect it if when unplugged it funs fine but really rich?
Thanks for any help! :D
