My tach hovers just above 500rpm and if I pop the hood I can see the engine vibrating pretty good, and just a slight tap on the throttle, to get it up to ~1000rpm and the engine looks completely still (nice balancing +1 Toyota Engineering!). OP, this is propbably the shaking your feeling, and even though it's normal, it drives me nuts cuz I like everything to be smooth. I feel your pain

Does anyone know how to tweak the ECU to make it idle a bit higher?

Just an update. I changed my spark plugs and filters. Only to suspect my transmission mount. Both the transmission mount and bottom motor mount were bad. Replaces those, and now the whole car just sounds rough. Im going to assume its the motor settling in. .. I love my car, but all this work is going to drive me nuts. I just hit 100k and have a feeling my Zippy is going to need alot more work. He still looks beautiful though.

Get thee to an experienced mechanic! Hopefully he/she can identify the problem for you at low or no cost, then you can decide if you want to do the repair yourself.
