I think I need a Turbo Control Valve = TCV and hoses for my 2001 Volvo V70 2.4 front wheel drive. I am not getting power when pressing on the gas pedal and it wants to stall. The car runs fine when first started but after it warms up and it is shut off it will stall when restarted and their is a lack of power (sometimes). If I keep the RPM's up by depressing the gas it will run (I have not tried to drive it this way). I already replaced the Mass Air Sensor and that did not help. I had my local Volvo dealership run a diagnostic test and they found "communications faults" with the ABS control module , the central electronic module , the Engine Control Module = ECM (Volvo wanted to replace the ECM wiring harness, they said they found some corroded terminals) and they wanted to replace the turbo control valve.
I was going to start with replacing the turbo control valve and do it myself.
1. Do these problems sound like a turbo control valve gone bad? or a plugged or worn out hose on the TCV or both?
2. Do you have a tutorial on the TCV replacement and it''s hoses I can view?
3. Do you have a tutorial on replacing the ECM wiring harness ?
Thank you for all of your help.
