My local garage has had it twice no issues on diagnosis, no compression issues, fuel filter changed suggested injectors. Main Volvo dealer, 3 diagnosis show no faults. Injectors checked, no faults. Petrol tank dropped and fuel pump checked no problem. No compression issues. Probe inserted via injector ports, blackened in one, spotless in another, two with what looks like small sliver of cotton shaped like an and sign.

Volvo dealer wants to take the head off and start from there.

The car starts first time, sounds as if it is missing, then runs ok , as I reverse it stalls. I start again sometime stalls sometimes pulls away.
