After a pleasant winter.........advice required
The old girl (147 Turbo Selespeed) had been so well behaved during this miserable excuse of lousy weather weve had until now almost.
From cold the car accelerates upto 2750-3000rpm, at this point there is several jerks, sometimes rather violent.
MCSF does illuminate sometimes, showing P0100 Maf Circuit A. MAF has been replaced with a new one (bosch), this has not resolved the issue.
Due to a failing temp sensor this has also been changed at the same time.
Once car is warm, as in the thermostat opens, the issue disappears, to the point where the MCSF light will go out and stay out untill the next time the car is run from cold. There still is some minor jerks when warm but nothing like when cold.
Battery has been tested this morning 12.08v not running 14.4v running so have ruled that out too.
Any advice would be appreciated as always.
