By the way are you running "speed density" setup, if so maybe a MAP sensor issue? Joe

I've thought about changing the injector on time, as well as changing the fuel accell enrichment. But in the past the car ran okay the way it is setup. So I want to find out what happened.
I have a hall effect cam position sensor, and a magentic crank sensor with a 20 tooth wheel. I'm going to try to check them today. And I've got a coil on plug tester on order.
I'm running in open loop (I think thats alpha N).
I have a thought that the problem has been "caused" or made worse by the use of the two step function. When I started trying it is when this problem started.
I'm on the way out right now to get a handheld laser temp gauge to check the different cylinders ( my hearders are wrapped so I can't do the spary bottle).
I trying to get another ecu to try. The map sensors are built in to the ecu.
