As expected the engine rev problem has been solved by a new MAF (multi air flow) sensor. The difference in performance is incredible and she now accelerates freely and rapidly as she should.
The suspension issue isn’t what we expected exactly. It’s the OSR top ball joint that is causing the creaking. The bushes also need doing. There is also some corrosion to the lower arms that needs attention – removal, shot blasting and re-painting. Cost will be a bit more than expected but not much more.
Unfortunately there is a leak on the PAS. If we have to replace the unit it’s big bucks for a new one or about £100 for a refurbished one from Autolusso. For now have put £10 worth of magic leak fixing liquid into the hydraulic fluid. Fingers crossed.
