how to advanced timing on a 1G

[1990boost]

i am having trouble passing emissions and want to advance the timing a few degrees to see if i can get it to pass, how do i go about doing this? thanks

Not to be a dick, but a simple search on here or Google. I'll even help you out. Have fun.

I don't think I'd recommend advancing timing without an actual tuning system like Link. You could be running into knock without knowing.

thanks, i did search but found not what i was looking for, do i turn the cam angle sensor towards the radiator or firewall to advance the timing? only need to do this to try to pass emissions then will put it back to where it was. just need to know which way to turn the sensor.thanks

Hey its his car, let him do what he wants to try and pass emissions. To advance timing you turn it clockwise.

i am failing for high CO levels so with a bit more timing the cyl will run hotter burning the fuel to help me pass

are you sure its clockwise? thought it was counter clockwise but want to be 100% sure..thanks guys

High CO's usually points to a bad 02 sensor. WHAT CAUSES HIGH CARBON MONOXIDE (CO)?


1. Dirty Air Filter
2. Faulty Oxygen Sensor (O2 Sensor)
3. Defective Manifold Absolute Pressure (MAP) Sensor
4. Defective Throttle Position Sensor (TPS)
5. Defective Engine Coolant Temperature (ECT) Sensor

Advancing the timing aint gonna help any (and the ECU will fight it back to where it belongs.).

First..to make it pass emissions:

CHANGE the OIL! dirty oil is full of hydrocarbons that raises up the HC counts real bad.

Then secure all vacuum lines, spark plugs gapped to proper measurements, and have the thing on *5BTDC with the ECU ground tap connected to ground.

Plain and simple. I had the same issue but doing above got me to pass with flying colors.

oil change is fresh, vac lines are all secure and tight, plugs and wires are also new, i passed all the test's except for the CO, hydrocarbons were fine, i tried again the next day after disconnecting the PCV valve to stop recirculating the fumes back through the engine and also added a gallon of denatureized alcohol since it burns cleaner, that helped drop the level some but not enough, first test co was 0.98% out of 0.80% allowed and second test was 0.94% out of 0.80 allowed so it helped but now need more help.. maybe a new 02 sensor will do it.

how exactly is it failing if it is just failing the sniffer then just mix a little e85 in with it not alot though maybe give it 3/4 tank and top off with e85

sorry didn't see the last post.

To advance the timing you move the cas clockwise as mentioned before.

also added a gallon of denatureized alcohol since it burns cleaner

Plan on a fuel filter pretty soon since this alcohol, being corrosive, will eat what it will off the inside of the lines and carry it down to the filter to plug it up...and the same with using E85.
