Hey everyone! I finally bought a code reader and tell you guys whats going on. Okay, hooked up the code reader and got the following fault codes.

The 153 and 155 togather is an important indicator that the wire harness to the front OX sensor on the driver side has a fault.
The sensor heater circuit is in fault.
Check the harness for a rub-through, a burn from exhaust, plug seating etc.
The 153 is saying the sensor is lazy operating.
The 155 indicates the heater circuit is not functioning in the sensor making it lazy in operation.
The reason is the sensor has to operate at near 600° F to work correctly but is now somewhat colder than it should be.
.
The 442 code indicates the gas tank evap test fails due to a vacuum leak. May be a faulty gas cap or some part of the test circuit is faulty.
The tank system is a sealed operation and is tested for this by applying engine vacuum for test and fault detection by test result sensors.
Note that if you clear any codes, the computer must retest a lot of functions.
The fuel tank usually takes the largest amount of time in drive cycles to compete.
Good luck.

Great Bluegrass 7, thanks for the info! I know for a fact that on the 442 code its the gas filler neck. Where the gas cap seats, a piece of the neck broke off, so I need to buy a whole new gas filler neck. As far as the other two codes I know how I am going to spend my Sunday! hahaha! Let you know who it all goes, thanks.
