my 16 valve idles at about 1500- 2000 rpm cold not 3000-4000. the throttle also started jumping around from 2800-4000 rpm. it would go up then drop over and over.

I have been driving it for a week or so. when I put it back together I didn't have a timing light, so I guessed and it runs okay, but not perfect. I got a timing light and when I checked to see what the disty was sitting at it was at about 30 degrees on the timing scale for the belt cover. Naturally I moved it. when I was talking to TT earlyer he said it needed to 8 degrees. I moved it there and it idled good but it didn't accelerate and when I shut it off it would not start at ALL. I had things to do so I moved it to 20 degrees and left for the store. I got about 3 miles down the road and then hit the first stop light. I came up to and shifted down to second the rpm was about 1500 the light turned green and i tried to accelerate, but it didn't. the rpm went down to about 700 and pushed the clutch in it went back to an idle rev ed it up stuck it in first while still rolling and went down the road no other problems. I got to the next stop light and came to a complete stop and took off and it almost died, but it didn't. when I got to the stop just sitting there it died. I got it started after some cranking and kept the rpm above 2000 and it wasn't that bad. my only thought is the timing belt is one notch off. it pings a Little when accelerating, but It doesn't want to be timed right. Sometimes it feels like a bad accelerator pump, but these don't have one. A low rpm it like a cold motor when you punch it it just dies. what do you think. right now I would just like to give these problems away for $1000 to the next guy, but I don't think I could sell it like that.

A bad throttle position sensor will give you a flat
spot if you punch the skinny petal too hard.

Try going a little easier on the throttle and see if it
stops doing it.
