VR6 Not Smooth

[justadude]

My 94 VR6 is not running Smooth

Diag Report

Intake Manifold Temp Sensor - Open / Short Circuit
HALL Sender - Open / Short Circuit
Engine Speed Sensor - No Signal
Mixture Adaptation - Adaption Limit (add Exceeded)
Lambda Control - Regulating limit not reached
Idling speed regulation - Adaption limit exceeded.

Hi

I was wondering if all of these need to be replaced which is rather expensive or if you guys out there can give me a better idea of which way to go about it and what to purchase first.

Any ideas would be greatly appreciated as it’s an expensive Diag report. Symptoms include engine cutting out sometimes and serious lack of power when going up hill.

Please guys. Let me know what I can do?

Thanks a stack

Since most of your components (if not all) are Bosch, I suggest finding another ECU. Plug it in and see if your problems magically disappear. Often times when Bosch ECUs start to fail, the diagnostics are the first to go and random mis-diagnosis happens. Its rare that all of those components would fail at once, so look to the computer first.
