Timing I just smoged my 1994 camry and the smog tech said that the timing is at 20 degrees does anyone know what the oem spec is for the camry?

run the fault codes
for the timing to be out there will ba code

timing on the chevy motors do not very much.
most of the older 350's timing are set about 8 deg before top dead center. some california smog certified 350 timing were set back to 0 deg or, at top dead center. check under the hood for a smog decal. it should have the timing specs, or it might say "timing not adjustable" or N/A. if it is missing the decal i would set it at 8 deg, road drive it, and listen for enging pinging on accelerating under load. if no ping i would leave it at 8 deg,if there is slight pinging i would ****** the timing in 2 deg increments until the pining stops. i would stop if i reach reach 0 deg or top dead center.

I don't know what the standard is for your state,but that doesn't
sound bad at all, for a 1994 spec vehicle.

How would they know timing was an issue?

I suggest your exhaust converter is worn out
May need a clean air filter
New O2 Sensor

Assume spark plugs aren't too old &
no ignition misfires?

Egr Valve ?

Then He did wrong. You are allowed 3 degrees out even 5 degrees. TPS replaced runs and quits.The way to adjust the TPS is to use a OHM meter till roating it gives no continuity.Leave alone for now,there is a idle up air control.on the throttle body its brass turn that 1/4 out and bring the RPM out. to 800RPM. When you moved the timing you also must set idle.To begin with the TPS was never the problem. Do the basic set timing,you also set RPM.

Firstly the no.1 piston should be at TDC (compression).

The upper camshaft sprocket has a smaller hole in the web. This should be lined up exactly with the TDC timing mark behind it on the cam bearing cap. In this position it will be vertically upwards.

At the same time the notch in the crankshaft pulley timing flange should be opposite the 0 degrees mark on the timing marks on the front of the lower belt cover.

The '92 Subaru Legacy uses a distributorless ignition system. No adjustment is possible/necessary. The computer adjusts the timing continuously.

You can check the timing if you have a timing light. The spec for engines with a turbo charger is 15 degrees plus or minus 8 degrees at 700 RPM. Non-turbo engines are 20 degrees plus or minus 8 degrees at 700 RPM.

At the base of the distributor there is a metal bracket with a bolt holding the bracket to the intake manifold. This is the distributor hold down bracket and you will need to loosen the bolt a few turns. A timing light is needed to find the correct timing of the engine, so connect one to the car in proper order. With the clamp loose and the timing light on, start the car and point the timing light at the harmonic balancer where the timing gauge is located on the timing belt cover. The light will show you where the timing is and so adjust the distributor (clockwise or counter-clockwise) until the desired setting is achieved. When the timing is set, turn off the car and tighten up the hold down bolt, be careful not to turn the distributor, and this is how to set the timing.

You have to remove the timing belt cover and slip off the old belt...The timing spec adjustment is: 10-15 degrees BTDC
