Hi!
I've replaced my gp 95 3.1L engine about 2 months ago.
ever since, the check engine light goes on after a while of driving and off after turning engine off and on again.
the scanner read the code 77 (EGR solenoid #3 malfunction) as history code.
I've replaced the EGR, but the code keeps on coming... (and as Historic code).
another problem (or is it the same?) is that the scan tool can't erase this code from the ECM, so I've erased it manually.
any ideas?
thx!
