2nd Gen. 91 Toyota 4runner 3.0 V-6 emission's failed twice?

One of the Cat's were replaced 2 year's ago and last owner said passed with flying color's. I replaced the actuator for the EGR(small round plastic deal with 3 vacuum lines coming out of the top and bottom), pulled the EGR out carb cleaner-ed it... also mechanic told me to run a quart of transmission fluid through a vacuum line on intake to suck it through the EFI system... the actuator brought down the NOX which is what I am failing from 8 to 6 what ever the unit's are the allowable limit is 4 so the actuator cut it down. After I cleaned the EGR and ran the tranny fluid through the efi system and smoked out the community for a square mile I had the EGR off and put an air hose on a vacuum line fitting on the EGR and it blew the rubber plunger material up and out of position. mechanic said I have to replace now because back-flow will happen after I blew out the neoprene... I am going to go to a pick a part here in PHX and pick up an EGR that looks OK and in good shape so the system will be back to where it was. so it was at 6 now after the tranny fluid to clean out EFI system and new EGR what else can I do to make sure that I pass I'm running out of time and money...































Thanks in advance for taking time to read my question and for your time an wisdom. \































I wish I could pick all of the answer's but I will do my best to pick what I feel is the best solution...

how much miles does it have, whats the condition. depending on these factors it can cause problems in different places. I suggest going to one good mechanic to take a look. You may also try selling the car because the time may have come to move on, espeacially considering its 19 years old. Toyotas can last a long time if taken properly care of, perhaps the previous owner did not take care of it and so that is why its it the cuurent state as it is
