didn’t meant to be a smart ass-not sure ot the age of the Impala you’re discussing but nothing is as confusing as looking under the hood of one of “today’s” cars-use to be someone could do some of their own repair work-not anymore.
Working on today’s cars is actually easier in many respects. The most difficult cars to work on are actually the carbureted domestics of the 70s and 80s with the billion vacuum lines that run for miles and miles all because the Big Three were too cheap to go to fuel injection.
Of course, it helps to have kept up to date on what’s what and not have buried one’s head in the sand with regards to automotive development for the last 30 years.
