Joel,
I'd still put a little suspicion on the muffler clog idea unless you've
actually run it w/o the muffler. On that run down to the gas station, maybe
you could do it with the muffler shifted over to the right, about 1/2" from
the Cat. It will be VERY loud, but could either eliminate the muffler as
potential source or pinpoint it.

Sorry for cross posting but there are experts on both lists.
It really sucks when you are the mechanic and you don’t know what to
do.... so with my tail between my legs I turn to these forums for any
assistance.
I have an 89 Syncro Westy with the stock Boston Bob 2.1 Liter gasoline
engine with about 20K miles on the clock.
Symptoms are that it start fine, idles fine, revs up fine without a load
and with a load it dies out at about 3000 RPM. So about when you engage 3rd
gear to get going ..... Nothing and it loses power from there. Luckily I
am in my driveway and not somewhere on the road in Wyoming.
IT was suggested to me, by several mechanics on site at Westies at
Watkins, who know more than me, to check the air intake, the fuel pressure or I
may have a plugged muffler/catalytic converter.
OK All good areas to focus on so the first thing I did was change the fuel
filter. No changes and I went from there changing and swapping one
component at a time and going for a test drive. Here is every component that I
have changed, tested, adjusted, syncro-nized and still I get no
satisfaction.
1. Fuel filter - new
2. Fuel pump - swap
3. Fuel pressure regulator – swap
4. Ground wire checked and cleaned
5. Temp II sensor - new
5. Air Flow Meter – swap PS (I have the Vanagon Syndrome capacitor
soldered into the AFM plug)
6. Air intake boot – swap - sucks plenty of air just fine
7. Throttle body cleaning and new seal
8. New vacuum rubber hoses
9. Air filter - new
10. Spark plugs - new
11. Spark plug wires - new
12. Catalytic Converter – see through baffles relatively new
13. Muffler – relatively new – no mouse nests
14. Oxygen Sensor - relatively new
15. ECU - swap
16. Distributor - swap
17. Coil – swap with another green coil
18. Timing – set per Bentley
19. Fuel lines replaced last year
20. good exhaust manifolds, no leaks
It's a real bummer; man!
The only other thing that I can think of is to swap out the idle computer
module behind the taillight since the sensors and ECU connect in on this
and it may send goofy signals to the ECU at various times.
Also I have not messed with the charcoal canister and that section of the
fuel venting system. Should I?
I will stumble down to the gas station and refill the tank with good high
grade gasoline just in case there is some bad fuel as well.
Are there any other things that I have missed? Any help or suggestions or
areas to re evaluate will be considered.
Thanks,
