error code P1384
how do I locate and replace knock sensor

The passenger window should go down a slight amount when the door handle is used; the window should return to the full up position when the door is closed. The driver side works normally, but the passenger side works correctly only a small percentage of the time. The electric window switch works normally. What is the likely problem and can I fix it myself?

engine hard to start and sputters while running

it was running very good then just stopped running have 1/2 tank of gas then just stopped i checked the gas coming out of the fuel filter in the back of the car underit there is no fuel coming out of it when the key is on just no fuel coming out. I thin it is a relay where is it.

rollbar light and rollbar switch light on all the time

I received the car with an empty tank of gas.I filled it up with 93 octane & a bottle of Lucas engine treatment.I then drove it to a laser wash.The vehicle performed great until I got home & placed the car in park.The tach started moving from 650 rpm's to app. 1300rpm's all on its own.It will only do this once the car is at normal operating temps.HELP!

I just purchased the car & it was extremely low on fuel.I filled it up with 93 octane/lucas engine treatment, & tokk it to a laser wash.It drives perfect on the highway,stoplights idling, but once you put it in park it will idle up to 1250-1300 rpm's then down to 600-650 all by itself at about 5 second intervals.Trash in fuel?MAF?
