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. Jim Davis In a message dated 12/12/2011 1:07:09 P.M.

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.
