trailing front and trailing rear not identical
the trailing on the 2 rotors. using a timing light. is not identical. on the front rotor. it is spot on. but on the rear. it isnt even any where near the pin to line it up.
it also runs very rich on idle. and i am guessing thats why.
what should i do next?

The leading plugs both fire at the same time as each other which is why you can see both of them at the same time. This is called wasted spark. The trailings do not. The front trailing plug should be visible on the trailing timing mark but since the rear doesn't fire at the same time, you won't see it. This is normal.

i am just checking everything over cuz i just changed out my TPS. and the car isnt running right. idle wants to drop to 500 when its set to 1200. and its 11a/f at idle.
Each engine like a different AFR at idle, just because stevensimon's car likes 14 or 15 doesn't mean every other engine will perform the same. I know for a fact that mine likes high 12's...
