Problems with dash lights and idle

Asked by Oct 12, 2010 at 05:54 PM about the 1994 Chevrolet Suburban C1500

Question type: Maintenance & Repair

When I start the car the dash lights, including radio, temp controls, etc blink and the idle is bumpy. If you hook it up to a computer it shuts the computer off and on. We have replaced the battery, check the alternator, replace the cap and rotor and the mechanic has no clue! We tried a new ECM and it did not work. Does anyone have any ideas on what could be wrong???
