So, since it started near the same time you changed the plugs, doesn't it make sense to check there first instead of starting a part replacement bonanza? That is a 90% probability. Plugs are rarely bad out of the box. I am not telling you what to do. I am telling you what I would do. I would check all the plug connections. I might even pull the cap to each plug one at a time and see if one of them makes no difference. After about a half-hour of logical checking, I run it down to my local mechanic-friend and let him figure it out. Some people claim they don't have the money to pay a professional. I don't have the money to throw parts at it.

I have had that happen where it is a bad wire. So my mechanic scopes it, finds the problem and fixes it in about a half-hour, charges me $40, including the wire. I get to shoot the bull with the guys instead of trying to figure out what the problem is with the ignition system which used to include a coil, condenser, points, wires, cap, coil, plugs and more, which is now a bunch of electronic goble de gook, complicated by a bunch of sensors, that you better have some equipment to check.

Please excuse my ranting. It is just so odd to try and do complex repairs on the internet.
