Re: Idle problem on 93 SHO
EGR valve? My 93 SHO mtx does not have one. I don't have my book with me to check the codes, but here where I live Shucks Auto parts will run the codes for free and give a readout of the problems. When I did the last 60k tune-up I had the fuel pressure checked and was told that it was getting low, and when it started to idle like you talk about, I was to replace the fuel pump, which I did. The problem did go away with the new pump.
