alright heres the deal i picked up a 93 civic from a friend for about $400. it was running fine until a few days ago when it started surging in power. it sounds kinda like its missing on a few of the cylinders or something. i have changed out the dizzy with a referb. thinking that would help but no change... well thats a lie it ran better for about 3 hours. i have also changed out the plugs and wires. i'm starting to think that maybe my timing might be off or the problem is internal. has anyone else had a similar problems? oh yea i dont know if this will help but when it starts to surge it back fires, smokes and then it wants to take off like a bat out of hell. acting like nothing is wrong with it. it only surges in low-mid rpm range(idle-3500) but only when driving.
