Re: [MBZ] Weird attack of sluggishness - W123 300TD
ALL: I got another attack of sluggishness in DC near the Jefferson Memorial after some high speed driving on I-395 coming back into town. This time, it lasted a good mile and nearly 10 minutes of driving at 10 mpg before self-correcting. I took the car to a local Auto Haus and they changed my fuel tank strainer. The one in the car was ORIGINAL 1983 vintage, and was BLACK and completely clogged with what looked like a coke residue. No wonder i had this problem when the tank was low. Maybe now I can actually let the fuel tank dip to R without becoming fearful. Thanks for all your help!

I have a can of Biobor algaecide that came with the car but the directions are quite complicated, not to mention hard to read, as they are printed in a twisted way around the can. Has anyone used this stuff? I currently have about 5 gallons in the tank (1983 300TD), or about 1/3 of a tank. Otherwise, I started it up today after a couple days rest and it ran very sluggishly for the first minute, then eased into normal operation (all flat roads). I ordered a tank strainer and install that after the Biobor treatment, if i can figure out how to do it. Incidentally, the inline fuel filter is sparkling clear - not a speck of crud in it. Another question - is it normal for there to be a release of air (or vacuum) when I remove the fuel filler cap? Thanks to all for your great ideas and input.

Re: [MBZ] Weird attack of sluggishness - W123 300TD
Sounds a lot like a plugged tank screen --as the fuel level gets low, all the slop collects in the bottom of the tank. Driving on the highway pulls huge amounts of fuel through the filters, even though you aren't using much, so the screen plugs and fuel delivery drops way down. As the lift pump slows, fuel collect in the filters and you have normal power. Time to remove and clean the tank, and replace the screen.

Then it took off again like a turbocharged bat out of hell. Is it a coincidence that this happened with the fuel gauge at 1/4?. The car had sat for nearly three months while it was getting its drive train transplant, but never had this problem until I started to take it on the open road. The main fuel filters are fine but I haven't replaced the fuel tank strainer. What I don't get is why it has these sluggo attacks only after a trip on the open road.

Re: [MBZ] Weird attack of sluggishness - W123 300TD
DON'T forget to replace all pieces of rubber hose between the tank and the main fuel filter, or else you might still have the problem. The hose can look perfect and let air in the lines, but that is generally about the same effect as having a plugged fuel filter. Your symptoms are more aligned with Max Dillon's remedy. It is easier, so I'd try it first! At 04:22 PM 10/3/2008, you wrote: Hey Andrew, you have the whole weekend ahead of you. Report promptly on Monday.

Andrew I'm just catching up with this thread. Sorry if I'm covering old ground. I've experienced a similar power loss on the highway. My wagon simply ran out of grunt without prior warning of any kind. It was indeed algae in the fuel. Now I have a cheap clear plastic fuel filter fitted inline in the engine bay where I can inspect it regularly. Finding a biocide was a bit tricky at the time -- the fuel companies couldn't help (didn't want to admit they might have water in their fuel) -- but I'm sure the treatments are more readily available now.

Re: [MBZ] Weird attack of sluggishness - W123 300TD
Andrew, If the tank vent is plugged, at highway speed a vacuum will build in the tank because the time-rate of fuel consumption is high. When you slow down and engine RPM drops, the fuel lift pump cannot overcome the vacuum in the tank and so your engine is starved of fuel. Test: Drive at high speed long enough to cause the condition based on past experience, then pull over and quickly remove the fuel cap. If you hear a 'whoosh' of air, the tank vent is plugged. -- Very respectfully, /s/ Max Dillon '87 300TD, 310k miles Charleston SC Digest lurker (on and off) since 2001 ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Weird attack of sluggishness - W123 300TD
There is a (likely formerly) clear plastic tube that runs from a fitting on the very back of the intake manifold, right up against the firewall, across the firewall thence to the ALDA, a boost pressure signal conveyor that controls how much fuel gets squirted, I guess. Or an overboost protection signal or something that controls how much fuel gets squirted (or not). Anyway, if that thing gets clogged (likely stuff that gets stuck in the little fitting on the intake manifold, inside) you have to take it off that fitting and then stick a wire or something in there to sorta ream it out. Or maybe that hose is cracked, broken, looks like some Home Depot rigid poly would work OK as it is just a hose, and the Benz part number is obscure. It takes about 5 min to do that, worth a try. --R andrew strasfogel wrote: I have never seen or worked on either the intake manifold or the ALDA. What does this hose look like?

Then it took off again like a turbocharged bat out of hell. Is it a coincidence that this happened with the fuel gauge at 1/4?. The car had sat for nearly three months while it was getting its drive train transplant, but never had this problem until I started to take it on the open road. The main fuel filters are fine but I haven't replaced the fuel tank strainer. What I don't get is why it has these sluggo attacks only after a trip on the open road. Stop and go driving is not a problem. ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
