Re: 95 g_m_c sierra
ok im so sorry for the way my post reads lol thats what i get for trying to use my stupid cell phone for it lol lesson learned
but this is driving us both crazy . because as far as we can tell there is only 2 things that control the EGR system and thats the EGR it self and the solenoid so after buying both new how can this still be ?

Re: 95 g_m_c sierra
check you pcv valve and the tube that goes to the manifold it could be plugged. had this issue on my 90 gmc it wasso full of carbon that is was causing pressure on the crank case to throw the egr off.
