Hi
Has anyone got any advice for me?
This vehicle looses power when accelerating on the highway. I only happens every so often and cannot be predicted. I have replaced air flow meter and o2 sensor both of wich were scanning faults. The fault codes have stayed away since replacing the parts but the problem remains. Have also checked intake system and fitted new fuel pump. The vehicle also has a strange vacuum type noise in the cabin especially on cold start up, almost like a leaking brake booster but happens when accelerator or brake is depressed.
Any advice would be appriciated
Thanks
