I have gone through the many pages about this, and unfortunatley seems like everyone found a different problem. Trying to figure out mine. I have a graph from a AutoXray scanner, and having problems pinning the problem. Has happened the past few weeks in cold temps about 25F through 60F. No SES light. TCC is locked during the problem, unsure about TCC duty cycle range should be at. No bad cyclinders are showing, so I assume at this point no misfire. Any help would be great, if you need other readings I can get them.
thanks for looking
edit: the white line is when it happens first, I think the hops in mph are the next few surges. The black line is the data showed at the third column
