I have replaced the spark plugs (which looked really bad) the plug wires, and fuel filter, and new air filter is comin in soon. But it drives fine until you get on the throttle then it stutters and jerks until 4k rpm then it just comes alive. So what do i try next is the timing off or the injectors bad (i just ran a tank through it with the fuel system cleaner in it). Its a 93 civic lx btw. Just wondering if anyone had any ideas of what might be causing this?

 

Did you replace the cap and rotor?

ps- one thread per topic please.
