Hey Jerry, Ok I got out there and hooked up back probes to evap vsv, removed bottom pipe and kept my finger on hose to check for vacuum. Had my neighbor start the car, and got no vacuum or voltage from idle. I had him rev to 3000 rpm and still got nothing. No vac or voltage. I than removed electrical connector from vsv and put twelve volts to it. It opened right up with a verifiable clik. I put vac pump on it and verified it was open. I also tested the evap canister by blowing air thru the tank line on evap canister and verified that I could not blow air thru the purge line, with shop air. I pulled hose from intake to evap vsv and verified that there is vacuum from the intake, so that takes the intake nipple out of being clogged. So, i guess that there needs to be a way to trick ecu to power up vsv valve. I am going to go for a drive with vsv line reattached to purge valve and see if i can get ecu to pop the 0443 code again. ok all i have for now. Bill
