Engine Mechanical problem
2003 Volvo V70 Front Wheel Drive Automatic 85000 miles
During the later stages of the engine warm up, the revs become unstable and when braking, dropping to 500 rpm or less and stalling.
Initially whilst the revs are artificially high all is OK, the problem only occurs as the revs start to drop to the nominal idle revs, about 900.
Once up to normal running temperature it steadies out and runs OK.
It has been suggested, by a Volvo main dealer, that it might be injectors leaking overnight, causing a too rich mixture untill excess fuel is burnt off.
Has anyone had any similar experiences?
have the same problem?
