raise the idle with that resistor guys. the idle is a factory spec 650-700 rpm. i induced a vac leak before to raise the idle (pulled that vac line of the top of the TB, closest to the front of the engine) it raised the idle...then the ecu "learned" and dropped it back down to 650ish when i plugged the line back in it dropped to 400 or so... then eventually raised back up to 650-700.. that resistor seems a permanent fix. 1 month so far

you can't just change the throttle stop screw, you also have to recalibrate the TPS when you adjust it! Also, yes change the front and passenger side motor mounts to start with.

my car shakes like hell as well, today for some odd reason it stopped for about a min, once it gets to 900rpms its rough, so i throw it in neutral and rev it to 2000 rpms and it is fine, but like clownprob said clean your throttle body, someone recommended that to me.
if theres a bottom end problem (balance, rod) it would get worse as RPMs rise.

i still haven't found the issue.. but that shiny new alternator they sold me at advance auto parts failed already its grinding inside.. going back today to exchange it... man i wanna junk this car but i just gave up my truck and sold my Mr2 so I'm stuck with this thing until I save up enough for something else.
well not to jack your thread. been searching for it but how do you change the idle i know its a screw on the throttle, any pics
The hard idle set screw is what the throttle pulley rests on, (half moon that the cable is attached to) comes to a stop at one end of the screw. There is a small nut to loosen it up and it is a small metric alan key which turns it if i recall correctly. The throttle position sensor will be out of sync if you change the hard idle.
Im following along mine just got back on the road and is now vibrating at idle a little once in awhile
having a similar issue.. haven't really done much yet cuz not sure where to start... my car starts fine.. idles around 1200 or so until it slowly drops to the 700 or so normal.. but then it will start dipping VERY low on RPM and almost die (like 200-300rpm).. but will keep running.. very rough idle... then after i drive for a few miles, its still running a little rough, but is back to idling around 600-700... any ideas??

on the rear of the throttle body theres a small plate thats mounted/shaped similar to the TPS.
loosen it and rotate it. it will adjust the minimum opening angle of the idle control valve

thanks! i found that and adjusted it so now it idle's around 1000... so hopefully if it tries jumping down low on RPMs, it will still have plenty of RPMs left..
however it is still running a little rough.. like i have a miss-fire.. so not sure if its still a vacuum leak.. or spark plug.. spark plug wire... etc... not sure what how to test next...

i would do a tune up if it feels like its misfiring

pull all four spark plugs(keep them in order) and closely compare the colors to see if one is rich or lean. Also try a cylinder balance test. With the engine running use a rag to pull the spark plug wires one at a time, the rpms should drop and the engine will run rough. If one cylinder has less of an effect on the idle speed when you pull the plug wire than that is your weak cylinder.
A compression check wouldnt be a bad idea either, they have a loaner one at autozone
