3 questions-vsv, door lock issue,and shocks

[beige97camry]

97 camry with 2.2 engine, auto trans,
1st.....took vsv off due to p0401 code, egr etc. checked good. vsv only messures .85 ohms so can I assume it is bad??
2nd ....when pushing auto lock on drivers door all doors lock except "sometime" drivers door, lock moves freely when manually pushing. is it the solenoid for the lock or something else, maybe sticking now and then....solutions???
3rd. .... car is mushy driving, pushing down on front end it seems firm with virtually no bounce, on the rear it is very easy to push down and has some bounce, is it the shocks in the rear or maybe springs. your thoughts... thanks.

Gonna answer 2 and 3:

2. Door lock actuator is out. Replace it. Replacing driver side power lock actuator

3. Its the shocks. Replace all four of them at the same time.

They are noted to have problems with the vsv egr but before you throw parts at it do this. To make absolutely sure the diagnostic steps are as follows. Start the engine, connect a hand held vacuum pump to the rubber hose coming off the egr valve, apply vacuum to it if it tries to kill the engine, the egr valve itself is working properly, (it adds spent exhaust gases to the incoming air charge therefore reducing the temperature of the combustion chamber during combustion, lowering the production of harmfull gases).

Next see if the intake is sending enough vacuum to the vsv to operate the egr valve, this is done by connecting a vacuum gauge to the modulator (a round plastic bit with a red metal top with 3 ports coming out of the sides, loctaed on the top of the intake manifold next to the throttle body). Connect the gauge to the Q port and open the throttle to approximatly 3000 rpm, the guage should read around 20 inches of vacuum.

If it doesnt check the vacuum hoses that connect to the front of the throttle body and if the are good replace the modulator. If it does pull 20 inches check the lines that go to the vsv, if they check ok then by the process of elimination, the vsv (vacuum switching valve, which opens when told to do so by the ecm providing vacuum to the egr) has to be the problem.
