Inconsistency

Too rich makes it too sensitive to temp and Baro changes.

I pay extra attention to my routine for consistency, especially since these issues have come up.

I have the RPM graphs saved as pdfs but am not sure how to post them.

I do not think it is jetting just for the fact that no big change in weather has to happen for the car to make a slow run. No matter what the weather does the 4th or 5th run will be .2 slow and if we make any additional passes after the slow run they are slow as well.

Targus, In the submit reply window, top row, there is a paper clip next to a smiley. Right click that & a window opens with a button to browse your computer for the files you want to upload & in the lower right of that frame an upload button. That said, I have never been able to upload a .pdf, only a .jpg or .bmp. Can you save the file differently ?

1320, how bout we help with his upload issue 1ST.

Attached are RPM graphs with the red line showing a "good" pass and the black line showing a "bad" pass where is slows .2

I haven't had the privilege of reading many of these graph's but with the black line rough, does the engine have an intermittent miss ?

While I was researching this site for possible answers to my problem, I came across your post and the graph (and inconsistancy) is similar to what I am experiencing. It started after I repalced the torque converter to a 9" unit that was made for my combination. I blamed it on the new converter but they told me it is spragless so that ruled out a rolled sprag. When I told them that I did not see this problem with the 8" (loose) convert, I was tolded the looseness masked the true problem. I have been going through everything trying to find what is causing this intermittent loss of power.
Did you find what was your issue?
