Hi I have a 02 virage txi. At the moment it starts and idles fine but cruising around it will start to bog out like its starving for fuel. It will run no more thean 10 min or so.
I kno its nmnot fuel pressure as I have pulled the gas tank and fixed the pressure regulator as it had fallen off n the pump. Now I have 25 psi.
I have also checked the EMM and water is goin thro it.
I am thinking it may b the throttle position sensor.
Does anyone have any ideas of what can b done to fix it?
