good, evap 1, far more easy, that is why i like 96 the best, the early ones are evap1,
im not sure, print out the freeze frame , for 443 failure. and we can noodle the data see if it is revealing.
the freeze frame stores the last failed DTC. if 443 then you have it stored in memory,just dump it.
it will show, all important PID parameter that are a snap shot during the failure.
other tests.
do you have vacuum at the back side of VSV purge idling hot>>? if not its blocked,
i think the valve is open at hot idle and you will have vacuum at the output of VSV too. check that.
then make sure that vacuum can suck and get air flow from the canister, this will be the tricky part., id use the vac too on the hose going down and not see it pull a vacuum.
if it did, the canister is plugged.
i wonder if it will throw codes for the hose removed to canister. vsv to canister. if not , that means the canister is plugged, up. or if you get a different DTC code. but the monitor is slow slow to trip off.
