Test parts instead of buying them to ensure that they are working before replacement.

Honestly, it may be carbon build up and incorrect oil so it's causing pre-ignition events. When's the last time you had your injectors cleaned?

You haven't told us enough to say for sure. Get your stuff checked so we know what's going on with the engine so we can actually know the deal with it.

Maybe, can't say for certain until we get some numbers. Compression numbers, sensors spec'd etc. If your compression numbers are low it may be carbon hold back some seals, but then again it may be time for a rebuild. If the injectors are clogged getting them cleaned and flow tested may actually be the best option. The problem comes from not being able to know if the AFR's are running rich or lean. Also, what are the conditions of the Spark Plugs?

Leading spark? Coil?

Do you have an ignition pack? Is it or the coil properly grounded?

TPS should have no dead spots and it needs to be within the specs (can't recall if you've set the tps).

Also what the hell is a "lither?"

you're not writing too well so I can't fully understand what you're trying to say....I think you said the misfire stopped but now you have no power when you floor it and the check engine light is on. Right?

http://rotarycarclub.com/rotary_foru...51&postcount=7

Check those ^^^^ links and start testing the TPS...

those directions are fairly simple to follow but the most important is making sure there are no dead spots throughout the whole range.
