Need help on engin problem
It was cold morning when my 95 s500 started very strange symptom. when ignition turned on engin started rev up and down crazy like you step on accelerater to get quick warm up but much more severe ( 1000 to 5000 rpm) until ASR (accelerator slip regulater) engaged with ASR light is on. Then calm down but idle is still bit higher (800-1100) than normal(600) and drives in limp home mode. After driving awhile until engin gets hot enough then starting is normal with idle is still bit higher.It happening every morning since then. Anyone familier with this please give an advice I will appreciate it. Thank you.
