I've been trying to find the problem for awhile and i'm getting stumped. When I accelerate my engine seems as if it wants to die out, i've looked at the air filter and have found an excess of fuel which seemed to me that its getting flooded. When i'm stopped or start the vehicle the idle goes from low to high it doesn't stay at a constant medium. I've checked the vaccuum lines and haven't found any cracks or anything wrong with them. I'm stumped and need some help hopfully finding out whats truely wrong with my vehicle

Try cleaning your throttle plate on both sides with choke cleaner. Then take and have him take a look at it. The injector lines under the maifold may be cracked and leaking.

I finally found a code reader for my vehicle, it was tricky but a damn good find. The codes that are coming up are for my O2 sensors so i'm gunna replace those and see what happens. It also came up with a faulty coolant sensor so i'll have to look into that as well.

Before you start replacing stuff check the wires and connection first. The wires run close to the exaust and may be burnt. If they are then you'll have to fix that as well. And the coolant sensor is probably bad, but check those wires as well as some of those wires go bad and the sensor leaks coolant up the wire so you get corrosion on them. If that's the case you'll need to change the sensor as well as the wire. Alot of sensors come that way. You should change teh coolant sensor first before the O2 sensors.
