Arleigh Gibson (Evanston, Wyoming) - 1988 Nissan Stanza
Arleigh’s car has two problems, both intermittent. At times, if he steps on the accelerator, the car won’t go. Also, the car does “the Elvis Idle”--kind of a stutter. Both problems seem to happen more on short trips, and in winter. Ray thinks it’s a bad throttle position sensor, though he’s not sure this car has one. Tom thinks the problem is a vacuum leak.
