On going issues with engine intermittently stalling in idle and surging/knocking while in motion. 2000 VT II 3.8l, driven just over 200k
I have previously encountered CAS issues, generally causing failure to start and stalling after a relatively consistent timeframe (CAS failing above certain temps)
Changed CAS on-spec with component sourced off eBay due to extended crank during start
Defect persists - engine now intermittently failing to start. Begrudgingly employed services of a mobile mechanic who confirmed a defective fuel pump (via slapping tank during crank). Replace pump and filter
After approx 2 weeks defect persisted. Mobile mechanic graciously interchanged DFI module with a spare unit, which from memory was the original component
Defect persists, mechanic returned and replaced CAS at no cost with a sensor I purchased from Holden (Delco)
After approx 2 weeks defect returned. On these occasions ‘Police mode’ reveals temp at failure as relatively normal at approx 80degC
At other random times during failure the engine will stall when reverse selected or revs will occasionally hunt when steering inputs made or even electric windows operated
One consolation is that the engine always restarts after failure
Apart from this, the ignition plugs/leads are relatively new and engine runs well at all other times with a consistent fuel consumption
So far I have calculated that my costs have reached approx half the value of the car
Please help me keep old faithful off the scrap heap
