My beloved 83 300 td wagon has started to shake wildely after warming up. When it's cold, no problems. The car has 152k miles and gets regular service. The car runs w/no problems when the idle is raised.

help!
fuel injector problem? vacuum problem?
all suggestions are welcome. I really love this car!

thanks,
Andrew

II have the same problem look at benzman5000 shakes at start up they said a disrtbutor or fuel injector you can find the distributer under do it your self

Andrew,

Do a search for Rack Bolt. I changed mine, and made a WORLD of difference. You need to have the engine hot to change it and get it adjusted correctly, so be prepared to spend a little while sweating over the engine compartment. I purchased mine for $23. An updated version came out in 1985, and it cures most of that shaking. Mine got so bad that people would stare at me at stoplights, and you couldn't carry on a conversation without your voice sounding like Catherine Hepburn. :)
Good Luck!!

84 300D-T

Have the compression checked! My '84 300D began to start hard, smoke alot, and sh-sh-sh-shake at idle. I spent time and money on the idle rack dampening srew, fuel filters, start of delivery timing adjustment, injectors, etc. before I threw up my hands in frustration and took it in for a compression check. The #3 cylinder made less than 200psi. One valve job later and I was back in business. The valve guides were worn on cyl. #3, preventing the valves from seating properly. I was told that even at 200K miles, there isn't much call for valve work on these motors, and I wouldn't jump to tearing off the head without the recommendation of a trusted and qualified mechanic, but the symptoms sound familiar.

Thanks for everything!!

I tried adjusting the rack bolt..NG

I searched on rack bolt and found a reply informing the owner of the vehicle to check the idle of the engine. I found by pushing on the engine "Stop" lever the engine smoothed out completely. I got my trusty manual out and found the idle adjustment screw, backed out the lock nut, made the adjustment, retightened the lock nut, and she is so smmmoooooth again!!! :)

Now.. how do I increase turbo boost? MORE POWER...I NEED MORE POWER!

THANKS AGAIN, ANDREW
