This forum is great, and I've learned a lot about my 1993 ES 300. I've got an occasional rough idle, which was a lot worse, as it used to cut off after at low RPMs, until on the advice of this forum, I did the following:
1. Changed plugs, wire, cap, rotor (plugs were bad saw an arc one day)
2. Cleaned injectors, throttle, replace fuel filter
3. Replaced Intake Air intake Hose (was cracked)
4. Replaced Engine Exhaust Flex Pipe (was damaged)
I noticed yesterday that my dogbone mount is loose and worn. Could this be the cause of the rough idle? I know there are some other possibilites i.e. EGR, Air Flow Senor, but I'm just hopeful that it's something as simple as the dogbone. I could probably live with the rough idle, but I ordered Motor Mount Set from eBay in hopes them would do the trick. The car runs smooth besides the rough idle.
Any other advice would be appreciated. This forum is the best. Thanks.
