I've had some symptoms start over the past few weeks. Rough running, missing, won't stay running...it seemed to get better when car was hot.

I did some research and thought it was the IACV as I was thinking it wasn't getting enough air during cold temperatures. Well, it warmed up and no change.

So, I read similar symptoms would happen with a problem with the PTU unit and cables, so I ordered a harness from Z1. It came and I have no idea how to install it, and there are procedures for splicing cables, etc.

Anyway, I decided to take off the two connectors from the PTU and used electronics cleaner and canned air to clean them.

VIOLA! That did it! My car runs like buttah now, and purrs like a kitten.
