I have optical points, but plan to clean injector points.
I have been thinking and believe my MPS is dead or out of wack
I am running rich through all RPMS. At idle I can get the co to acceptible levels , but at 2500 -3000 rpms it jumps up significantly.
My plan is as follows, see if it will make sense
set timing
set ecu to mid point
remove TPS connection
set co at 2% with rpm at 2500 using MPS
return and set idel CO at 1.5 -2% using ecu??

right now ecu is set to almost full rich , if I move to lean she about dies. which makes no sense , but gotta try something
its burning so rich that the inside of the tail pipes are pretty black ,and if you are around the car for any period of time your clothes smell like unburned hydrocarbons
Im not allowed in the house if I am working on her while the engine is running

injectors are rebuilt and balanced, no vacuum leaks, pertronix points, fuel pressure and running vacuum at specs, so its has got to be timing /mps /ecu what do you all think

also in regards to reading timing marks looking down at engine - left of top dead center mark is considered BTDC, to the right ATDC????
