Good weekend all.
My 1990 Pickup 3.0 L V6 3VZE is experiencing an intermittent problem with the EGR system (check engine code 71). The check engine light will turn on and off, often during highway drives several times. If it starts out with the light off, it may come on during the drive and if it starts out with the check engine light on, it may turn off during the drive...
Is there a part of the system would be most likely to fail occasionally? The valve itself? the temp sensor? the solenoid?
Any suggestions?
Thank you.
