I have a couple of bins of parts that came with my car - I believe they are all 1.7 related FI stuff. As I am switching to a 283 I don’t need any of it.

2 computers with harnesses attached - $100 each or $150 for both shipped in conus/Canada

Manifold pressure sensor $75 shipped in ConUS/Canada

Oil bath air cleaner - $40 + shipping

A bunch of other parts.

MPS Diagnostics
Before proceeding on any calibration or adjustments of the MPS, it is essential to check the basic operation of the unit:

Using a hand vacuum pump with a gauge (e.g., Actron model from Checker, about $30), pull a vacuum of 10 in. Hg on the sensing port of the MPS. If a vacuum cannot be pulled or it leaks down (< 5 in. Hg in one minute), then the sensor is leaky and must be repaired.

If the vacuum test is passed, check the coil resistances. The primary coil is measured between terminals 7 and 15 and should measure about 90 ohms. The secondary coil is measured between terminals 8 and 10 and should measure about 350 ohms. Also check the coil isolation - there should be no continuity between either of the coils and the case. If any faults are detected the MPS is defective and must be replaced.
If both tests above are passed, then the MPS should be in good condition. However, it is possible that one or both of the aneroid cells have failed and are no longer sealed. This failure causes a rich part-load and idle mixture. Testing for a failed aneroid cell requires measurement of the inductance vs. vacuum characteristic of the MPS. The recommended inductance meter for this test is the Wavetek LCR55 (~$175) . The slope of the part-load characteristic is compared to the calibration curves presented in this document. If the slope is significantly (~50%) less than the calibration curve, then it is likely that one of the cells has failed.
