Engine shakes when idling

SOURCE: 1985 toyota 4x4 22re missing and rough idle

Have you pulled out the spark plugs to see if there are any tell tale signs on them.They are a good indicator of many problems that occur and can save a lot of time isolating the problem.They should all be the same colour.Is the air box and lid properly secured with no leaks or splits in the intake tube.Have you put injector cleaner in the fuel tank to clear up any possible dirty injectors.Therse a few things your problem could be including engine vacuum leak which you can find by lightly spraying carburettor cleaner around suspect places such as inlet manifold and around injector seals.

Hi, Check all vacume hoses and fittings make sure there are no vacume leaks also make sure ignition timing is correct.

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

I've got exactly the same problem in '93 Camry w/5SFE automatic w/248,000mi. Transmission shop I trust told me ****** was gone. Another mechanic said the same. I'll drive it 'til the forward gears stop working. Forward L,2,D work great, except downshifting doesn't slow the car at all, although the engine goes to idle.

Let me know if there is any easy fix! Already did a fluid & filter change. . . .results no change. Thanks, cc
