Try cleaning out the throtle body with carb cleaner as there will be alot of oil vapour blocking all the little holes in it.

How to tune up a 1995 Geo Prizm? not passing smog, They told me to tune up and get new cataylic converter, but wont guarantee it will pass smog test.

A tune is just replacing the spark plugs every 100,000 miles and the air filter every 30,000, clean oil is also a help in passing smog, the new converter is what will most likely do the trick.

The system has to see a wide range of conditions before a smog test can be done. On most brands you have to drive at least 50 miles, at various speeds including stop and go, let it idle for 5 - 10 minutes, and run at freeway speed for at least 25 miles. It also has to reach normal operating temp of 195 degrees.

I have a 91 tercel that will not pass smog, unable to read codes, idles too high that if you put the car in gear before it warms up its jerks hard, appears to idle normally after warmed up, smokes pretty...

The smoking is probably due to worn valve guides.. the oil from the top..the head.. is leaking past the valve stem into the cylinder.. next morning or a few hours later when you start the car.. it burns this oil up..and the problem although still there is much less noticeable.. cause the amount leaking is's being burned as you drive.. otherwise it takes a while for it to accumulate.. It could mean a minor head/top end rebuild to a minor overhaul..

The emissions problem and the idle problem may be linked.

First make sure your throttle cable is clean and working properly. They can get dirty.. sticky..or even a weak spring.. but dirt rust and grime..biggest culprits.

There is an IAC (Idle air control) valve attached to the throttle body.. you may be able to spray carb cleaner into the closed throttle body to clean it.. You may need to replace this part. It can really get clogged with carbon.. and cause this high idle problem.

Next.. replace or remove/clean/reinstall the EGR valve...probably better off just replacing it.

Check all vacuum lines for cracks..replace as needed..vacuum hose is cheap.. and lastly.. do a minor tune up.. plug wires.. plugs (properly gapped of course). air filter and fuel filter..

Your car will probably pass the smog check even with the cold startup burning oil issue.. that's not what's causing it to's the EGR valve and possilbe lack of recent tune up.

You can continue to add oil between changes.. use a heavier weight.. and check often.. Once consumption gets more than a quart or so between can contemplate the real fix... or start pouring anything with the word miracle into it.(grin).

Great little car.. Best of luck!

Evap Sys Monitor

if evap is the only monitor that hasn't set yet, the car should still pass, a car is allowed to have 1 monitor that isn't set and still pass as long as the check engine light isn't on. take it in for the emissions, it should pass.
