the motor came from my other supra that was totaled but it was the same year. how do i test my egr and is it possible to remove it with the engine still in the car

Oh.... just noticed you're in Cali.... you'll have 2 oxygen sensors, 2 cats, 2 EGR VSVs and an EGR temp sensor to inspect on top of the AFM and EGR valve. First and foremost make sure the plumbing from the valve to the intake is clean then check for error codes in the ECU.

Check: Dashpot, EGR,

Check air flow meter, EGR gas temp sensor, oxygen sensor and sub-oxygen sensor:

Yes, you can remove most of the EGR components with the engine still in th car; The cooler plate is a MAJOR pain though and unless it's leaking it probably doesn't need to be removed. Just test it as shown above and clean out the plumbing for it. It's not the cause of high HC; It's the cause for most high NOx numbers (which you also failed on).

This covers all the likely suspects.

Is there much oil coming through your PCV system into the intake?

ur way off i dont have 2 of none of that, my supra is an 87 7mge thus im pre obd2, i have one cat, one o2 sensor, as well as one egr. but yea do you think my cat needs to be replace. as well as me actually changing my rotor and distributor cap.

No, I'm not way off.... it's SUPPOSED to have all of that if it was sold in the California market. It has nothing to do with CANN, OBD, OBDII, etc.

A new cat probably wouldn't hurt, I'm surprised you haven't been referred to a ref yet... but I don't remember how it all works there... just that's it's worse than here.

Test for faults in the current hardware before you start just blindly throwing money at it. If the rotor and points show significant deterioration you should replace them anyway if not though then forget it.

I pointed you where to find the diagnostic info you need to use, it's up to you to do so... I'm out.

my supra isnt a california vehicle. so what else can i check and do

[looneytune_2004]

are the emission standards differnt for a california vs federal vehicle?

[btwilson86]

They're designed for different markets, and the emission components on that vehicle reflect their intended market. IIRC, California requires all vehicles licensed in the state to conform to CA emissions. So your federal emissions Supra has to pass within the same levels of CA emissions Supras.

I read somewhere on the CA DMV website that they don't suggest importing a federal emission vehicle into the state because the cost of converting it would not be worth it. I believe that statement holds more truth to newer vehicles though.
