Message: Senior Citizen needs info. Engine light on. I had heard you can determine code by sequencing ignition switch? How do I do it? Truck is "juddering" at 2-5mph. Feels like brakes grabbing. Last time I had engine light on, took to dealer and was a module in trans, but only happen after driving in rain. Went away after truck dried out, but cost $58 to find out code number. 98 V6 4wd with 32000 miles thanks for any help. Gordon
