Great start 😎👍
👏👏
I hope you touch on the fuel injection systems of 1980 Chryslers in a future video. My dad had a 1987 Reliant and I had a 1987 Caravelle. The major headache we had with both cars was the faulty fuel injection electronics. On my Caravelle, I had to replace every sensor and the computer after 50K miles. The system on my Dad's Reliant was just plain wackadoodle. Was there an issue with the suppliers for the fuel injection electronics?
I haven't heard of this before, honestly, at least not so early - I'll refer to Pete. Sometimes I've seen relatively simple problems misdiagnosed repeatedly by dealers - I had one car make many trips back and forth before I bought the technical service bulletin book, found the symptoms, and fixed it in five minutes! No shortage of bad dealers racking up warranty hours in those days. But I'll ask Pete.
CudaPete passed on that one issue is the gasoline was blended for carburetors still, and had some particulates in it, so the fuel injectors could and did get clogged (I encountered this myself and the mechanic fortunately cleaned them as the first step!) - and the mechanics were mainly unfamiliar with (and often angry about) the new systems. The electronics were usually very reliable. You might also have had that other thing - “bad luck”!
@@motalesdave Thanks for the information. I never had problems with the injectors, just the electronics. I would've chalked it up to having a lemon if it hadn't been for my father's car having similar issues. All I can say is I never bought another Chrysler product again, although my brother had a Plymouth Sundance that lasted him nine years.
@@neal1964 Reminds me of all those people who replaced their "bad" Chrysler electronic ignitions when mechanics didn't understand they could just swap the $2 ballast resistor...! (That was far too common in the 1970s and 1980s.) That said, 1987 was the first year they ALL had electronic fuel injection...
I'm a quality engineer in medical device manufacturing. I'm my word FMEAs live in excel. DOEs in Minitab. Will you touch on Gage R&Rs?
Pete told me: “It was the 1980s, we did it all on paper.”
FWIW (and this is Dave here, NOT Pete), I've used Minitab but not for many years. I use Jamovi for quick stuff and an older copy of SPSS (before it was subscription only) for more involved work. But I'm not an engineer, I just do statistics. If I was doing a Gage R&R and I knew Minitab, I'd use Minitab... but I'd probably search Jamovi and JASP to see if I could do it there, at this point. Both are easy to use front ends for R. I vaguely recall the main advantage of Minitab was being able to feed your results back into a data set which isn't something I've ever needed to do. I'm obviously not a Minitab expert though! It's been too long for me to remember the other advantages.
Pete added they did do some things on Lotus, and the supplier survey did check to make sure they had R&R processes and such, but he didn't want to get too technical. Most was still on paper. Even the charts... which I find kind of interesting since I remember using a plotter in 1981, and my boss at the supermarket company in 1983 or so bought an Apple II and brought it to work so he could do spreadsheets!
