Mechanic says intake manifold replacement might help, 1000 to replace. Someone told me to use gas-line anti-freeze to beat the test...will that work?

It's a '98, so the OBDII codes may give a hint to what the problem is. Quite a few people here say Autozone will read it for free. I'm still outta country, so I don't know.
That %$^^$ is no mechanic.

If there aren't any aftermarket parts on the car failed systems is the only possible explanation. However- the intake manifold has *very* little to do with your emissions. The tech that failed your car should have given you a form with your totals. The different peaks will tell you whether the car is running lean or rich, and if your catalytic converter is functional.
Additives that allegedly help you pass emissions really don't make that much difference (if at all).
Seek a second opinion and *do-not* mention that the other mechanic wanted to sell you an intake manifold. (Or he might agree and try to sell you one himself!)

Any answer with "might help" in it is wrong. The smog check should indicate which systems failed. It can be as simple as a $10 oxygen sensor, or as expensive as failed compression rings requiring an engine rebuild. Gas additives that increase combustion help a little, and can make the difference in marginal cases, but probably not if you are double the limit.

No the fuel additive won't do the job.
There are 3 pollutants that could have caused your failure. The mechanic should have told you that diagnostics were necessary. The engine could be out of fuel control (probably) or the cat could be failing, or both.
E-mail me with the test results (all of the levels) and the engine, mileage, and the other test results (functional, visual etc.) and I will try to give you some direction for diagnostics and possible repair.

The intake manifold doesn't have anything to do with the problem, the problem is really in the sensors or air filter to dirty, for example injectors clogged, faulty MAP sensor or MASS sensor (depends on application) and the most important oxygen sensor and coolant sensor.

Get another opinion. Get a tune-up. Change the filters. Get the aftermarket junk off of it, if you have any....
