Computer problem
1994 Chevy Lumina 6 cyl Front Wheel Drive Automatic 200000 miles
----------------------------------------------------------------
I have had diagnostics run to find out why I have an intermittant cut out/power loss when accellorating. the failure codes are qdm 1 & qdm 4 but would like more detail as to what to do to correct this problem. If there are terminals that need to be tested, like 80 & 81, where are they so I can test them etc...I am a qualified mechanic and do most all my own repairs so be specific.
