this has been an issue for a long time but I still cat get to a final answer about it ... I just need to know if the AFM is not tunning for smoothest idle at a cirtain point but to unscrew the pot. and move it up a bit, but when full throttle the engine cuts off at 5300RPM, does this mean that the AFM is dead !! I also noticed that the spring is getting loose !! if I kept the spring where is it, the pot goes up and down and rpm sinks as if the engine is going to stop.

I made a vaccume check and was all ok ... I already have a good O2 sensor ...

if there are some steps to fine tune the engine to the max torque and smoothest idle I would be happy to know for sure ...

thanks ...........
