The Xterra will idle very high at times while parked. When driving, it will shift very hard into the next gear and rev until you let off the gas.
Noticed yesterday, a strong gas smell near the rear right side of vehicle.
Had a mechanic "fix" what he said was the throttle plate that was sticking. That worked for awhile and the car stopped shifting hard and the idle was normal. Now it is back to doing the same thing. What do you think this could be and will it be expensive to fix?
