It's an 18R - thats the problem :D

I would start looking at your ingintion system. Pull out the plugs and see what they look like. Also check your coil and leads when you check the points and a reaqly close look at your dizzy.

I had a similar problem in my celica once, turned out to be the coil, ended up replacing the dizzy, rotor cap, coil and leads and she ran better than ever before. But the best thing I ever did with that motor was ditch for an import engine. :twisted:
