I have posted this one earlier but now I can add stalling at the toll booth. Car stalled at tolls; restarted after 3 tries. The remainder of the trip (5 highway miles) it burped only twice more and thankfully got me into my garage.I have read the postings referring to fuel pump relay and fuel pressure regulator. I can now add these to the idea of a failing throttle switch. I keep waffling between fuel and ignition, driving myself nuts!
