Since the new motor early this year, i have occassionally got the random misfire code.
I know the TSB says that anytime a clutch, flywheel, conververter, balancer, etc.. is you should relearn the crank sensor. I was unaware of this until just a little while ago.
There is a Ford dealer next door to Finish Line where I get my work done. He had one of the tech's come by yesterday and we hooked it up to do the relearn.
There are a few boxes and one of them has a 6 in it. On the screen it says it will go to 0. I'm assuming it counts down as you are doing the learns.
You have to take the rpms to between 3400 and 4000 and then let off quickly.
We tried hitting the throttle probably 15 times last night. Sometimes it would come down slow, sometimes faster. Sometimes very slow. But, the 6 never counted down.
The tech had never done the relearn and wasn't even familiar that the new cars had them. I asked at my dealership and no one hear has ever done the procedure either.
Is there anyone that has personally done this that knows what we might be doing wrong?
Our other theory is that some of the "hard codes" could be keeping the car from learning. There is no CEL, but the IDS picks up a couple things like fuel pumps, fuel level, etc.. since none of the stuff is plugged in.
One of the codes though, is MASS Air out of range. This is due to the tune recalibrating the maf. IT's not a code that sets the CEL but a code the IDS sees.
Anyone have any insight to the relearn procedure. Do you need to crack the throttle fast, run it up, what. I know if you get much over the 4000, it will just keep the rpms climbing slowly. You have to kill the key if you get over the 4000.
I asked Jon and he said the codes shouldn't affect it, as evo's car had no problem relearning the crank position sensor and that was with a big procharger and a c4.
Just wondering if we are doing something wrong in the relearn procedure. The IDS seems to walk you through it, but now I have a steady light saying Crank Position Center learn not completed.
