D-jet troubleshooting, Only one item left on my list! Options

[saigon71]

My 1974 2.0 D-jet is running very strong, but there were two lingering issues with the FI that I wanted to address over the winter:

1. A severe idle "hunt." The engine would rush up to about 1200 RPM, then nearly stall...repeat cycle.

2. Every once in a while the car would buck, most notably at highway speeds...it wasn't bad, just annoying.

Last week I installed a new circuit board in the TPS purchased from Dave Sprinkle a few years back. It was calibrated according to the Pelican tech article using an ohmmeter.

I took a 210 mile road trip over the weekend to test things out. The car now idles perfectly through the entire warm-up sequence. Thanks Dave! (IMG:style_emoticons/default/beerchug.gif)

The problem is that I still have the same bucking issue. All my research points to the TPS. Any suggestions on what to check next?

Thanks for all of the suggestions. I'm going to remove the air intake temp sensor wire first and test this weekend. What is the recommended coil, the regular Bosch blue or a Petronix Flame-Thrower? BTW I have points in mine. New points, condenser and gapped correctly. Timing and valves recently adjusted.

Also, I've already cleaned the trigger points.
