Slow Down Lite On/Off

Your symptoms indicate that the over-temperature system is working correctly (what a surprise ) -- i.e., you had a real problem (low power, rough running) and the exhaust temp increased to the "blink" threshold. A 1982 US 308 doesn't have an O2 sensor. The first thing you should check IMO is your 5-8 ignition system -- e.g., check the extenders for burn holes/opens, put a timing light on each wire to confirm/deny spark, measure the cap contact -to- end of extender resistance, have a look at the cap-rotor-carbon button. If all seems OK there, you can try swapping DigiPlexes, but if the ignition seems OKish, but the bad runability remains then you have to start into the injection system. Good Hunting!

 

The stock F mufflers tend to be asymmetric inside, so unless you have a Tubi, or some other aftermarket muffler that has a symmetric design, I don't think you should put a lot of significance on that difference -- is your muffler stock?

 

My '87 328 runs fine but always has about 2 twice as much exhaust coming out on the RH passenger side as on the LH drivers side. My mechanic said they all do that... stock ones anyway.
