I was going to enrich the lower end of my fuel map tonight. It won't take long to double check the TPS, so might as well, right? Now, what did I do with that jumper I made to go into service mode? I spent time last night and this morning looking for the programming cable to the FI Tuner Pro. We moved to a new city a few months ago and I'm still discovering where some things are!
Thanks everyone. Been making small changes to the 2% to 5% throttle position part of my FI map and the mis-fire has already improved to a slight stumble. Even this is an improvement, but I think with a little more tweaking I should be able to clean up the stumble. Thanks for the encouragment.
