If I get rid of my EGR will it mess with the computer????

 

May set a code sometimes. Mine never did. Could also cause detonation if you're running too much timing.

 

WHAT DO YOU MEAN "DETONATION IF YOU'RE RUNNING TOO MUCH TIMING"??

 

The egr valve recycles exhaust gases to cool the combustion chambers. This helps to reduce detonation. If your engine has a lot of carbon buildup and/or a lot of timing it could be prone to preignition and the egr may be helping to stop that, so removing it could cause detonation. May not be, though.

 

EGR typically functions at 30-60mph speed with a warm engine. It introduces some exhaust gas into the mixture to dilute it causing reduced emissions and as was said lower combustion chamber temp. It's a pretty passive arrangement and doesn't do much to hinder performance. Biggest thing to look at is whether you have to pass an emissions test or not. It also will cause the SES light to come on intermittently as the O2 sensor will most likely swing out of range under differing vehicle load conditions. I would leave it alone, messing with electronically managed engine controls is almost always counterproductive and usually leads to poorer performance and decreased engine efficiency.

 

No it will not set a code.

No it will not do you any good, and may be a step backwards. Leave it alone and in good working condition as long as you keep the computerized setup. It helps the engine get full timing advance under cruise conditions which helps gas mileage, and does no harm at other times.
