Here is the story:
I've got a 99 Maxima GLE with 103K miles. About three weeks ago my check engine light came out. Took the car to Advanced Auto to get the code read and it turns out it was the Knock Sensor and the EVM Sensor. Took the car to the shop and they replaced the Knock Sensor, but the light still wouldn't go off and now it is throwing the Evaporative Emission Control System Pressure Sensor Malfunction (P0450). So I left the shop with the EVAP Pressure Code not being replaced as the guy said that it won't hurt the car to drive it w/the sensor blown but that I won't pass VA emissions.
Is this a common problem?
How much am I looking into for repairs/part cost?
With the P0450 code blown, would it affect or result in the fact that when I get gas, the pump keeps kicking on me so I'm constantly fighting with it to find the sweet spot (this started happening about the same time the check engine light came on initailly, but I attributed it to the specific pump)?
Can anyone offer advice on why the gas pumps would keep kicking eventhough the tank is nowhere near full?
Thanks in advice.
