B230F TB, TPS and Link Rod adjustments, OEM or Aftermarket? 700 1991

... "2.2lh,2.4lh and regina are all different. You need to determine which you have before adjusting. I believe the 91 B230F has the 2.4lh ie no idle bypass adjustment, no adjustment on the AMM." ...

Your mention of the 2.2 and 2.4 is an entire ECU engine system. My post did mention having a Regina system, so I do not need to determine that twice.

But I disagree anyway. Regina has nothing to do with the physical throttle body. Regina is an ignition system. So far, I have failed to see why the adjustment is the way it is, even though the idle is Controlled by the ECU (BTW a non-Bosch ECU). AT any rate, the 2.4 Bosch and Regina have the same physical TB.

I do agree that the 2.2 was adjustable via the air bypass screw under the left side of the TB. The 2.4 and 3.1 have no such feature. But they still need the TB physical adjustments. And I do agree and disagree that there is no adjustment on the AMM. There is no adjustment because there is no AMM on a Regina car. Regina uses a Intake Air Temp Sensor in combo with a MAP Sensor.

Oh Well, back to square one - can someone help with the problem?
