armin922 Posted August 12, 2009 Report Share Posted August 12, 2009 could a bad egr valve cause a car to feel like its going to stall and idle rough? a friend of mine is having that problem, they got it scanned and it said egr and im pretty sure they need a new egr valve. It feels like its gonna stall and when u acclerate it sounds like its hesitating. Quote Link to comment Share on other sites More sharing options...

87GT Posted August 12, 2009 Report Share Posted August 12, 2009 Just remove it and deal with the CEL that's what I do. Instant fix once it is disconnected. Quote Link to comment Share on other sites More sharing options...
armin922 Posted August 12, 2009 Author Report Share Posted August 12, 2009 so what exactly does an EGR do? what will happen if i just go trowas way and just disconnect it? Will it do anything bad besides the CEL being on? Quote Link to comment Share on other sites More sharing options...

It is some kind of environmental thing to get less Co2 into the air. The car will run fine without it hooked up you just usually get a CEL.

I just pulled the plastic tubing off the EGR that runs to the crank case and it fixed it for me. It can vent it out into the engine bay for all I care Quote Link to comment Share on other sites More sharing options...

The EGR takes the inert exhaust gas and re routes it back in the combustion chamer to reduce combustion temps lowering Nox emmissions Quote Link to comment Share on other sites More sharing options...
72POS Posted August 19, 2009 Report Share Posted August 19, 2009 what kind of car/truck you refuring too? the Gm 4.3's have normal EGR issues. that are easy repairs. 90% or more Ford's have some sort of EGR code in its history. I haven't seen anyone mention that your fuel mileage will also suffer with out the egr working properly. Mike Quote Link to comment Share on other sites More sharing options...
