You have extra air leaking into the intake manifold that mimicks a throttle that is open further than it really is. Check for vacuum leaks.

One common problem is a vac leak or a sticking throttle plate.
The computer controls idle speed by how much air is allowed into the intake. The idle control valve could be sticking even tho you have cleaned it, or have a faulty motor.

Idle Rpm Too High.


A high idle is caused by either a massive vacuum leak or a sticking idle speed control valve. I would think you have a vacuum leak, use a can of carb spray and shot around the top[ of the engine, if you hit a leak the engine will sound different, repair as needed.

1994 22re engine surging idle when brakes applied cause?


Check for a vacuum leak in the vacuum assist diaphragm. A leak can allow far too much air into the intake manifold, causing an increase in engine speed.

1. check your fuel filter and replace
2. this sounds to me like you are losing power due to your valves being out of adjustment, valve lash adjustment should be checked at every tune up on this motor
3. a manual on this vehicle would be a great asset to you

1990 toyota camry 4 cyl fails HC part of CA smog test in idle. Also idle varies by 200-300 rpm and when driving the power really surges close to 3600 rpm. Could it be an O2 sensor?


try using 93 octane with some octane boost. get the good octane boost that cost about 7 or 8 dollars. Fill her up .drive her for about 200 miles so the octane boost can clean
