Very strange deal here. I changed the fuel filter as preventive maintainance. Just bought the car last week with 146,000 on it, and no record of a filter change in the receipts previous owner provided. Purchased NAPA silver fuel filter Number 23023. Free flowing when blow air through it (lung power).
Replaced old filter - new one is correct side up up (inlet outlet corret directions). Engine now running very high idle, idle drop is off, and some surging at the high idle under drop.
Tried pumping fuel through new filter into large jug - great fuel flow. Pulled old filter out of trash can and tried blowing through it. Extremely plugged, no flow, can barely force ANY air through it.
Old filter bad, new filter good, car running like sh#$. Tried idle adjust down - bottomed out and still no good. Checked all nearby vacumn lines in case I knocked one lose - no sign of it.
Last resort, pulled battery negative lead to let computer reset just minutes ago. Understand it must be no juice several hours to reset?
Any ideas - need car for work tomorrow. Hate to put the plugged filter back on - seems I'm asking to get stranded.
Thanks
