What kind of modifications are likely to affect the EGR? I have been reading some horror stories about EGR problems and would like to avoid them if possible. Also, on a side note when I put my truck into 4wd, especially on the fly, my A/C goes through my defrost for a few minutes and then corrects. Any advice on the cause and solution? I appreciate all the great advice I received from everyone so far!
