I am the new guy on the block so if I do something wrong please let me know. My problem is I get a flashing check engine light at freeway speeds. I know this means random engine miss but I can not feel anything wrong seems to be running great no loss of power. My truck is a 2002 GMC 4X4 2500HD with 8.1 and allision trans. I have replaced the crank sensor a few months ago because it would die while being driven around town. This cured that problem. I have replaced spark plugs and the wires are in good shape. Thanks for any help someone might have on this problem.

  Probably should check it while running. Like an auto transmission. Record it and check it from there.

  June 19th I will receive my third joint replacement in 54 weeks! A well meaning friend said, "In a year you'll feel like a new man!" I'm sure I will feel much better a year from now than if I didn't have the surgeries, but I'm not expecting a reversal on the impact of aging. I try not to waste time "waiting" to feel better. I won't be able to drive for at least six weeks following my upcoming right knee replacement. I've started looking for a used mobility scooter or electric trike or mini golf cart to rent/buy that can take me to the local malls and shops. I know my wife will drive me wherever I need, but if there are tools to help me maintain independence, I will take advantage of such devices! I am sure there are members who have experience shopping for a vehicle that doesn't require a licence or peddling! Any recommendations?
