Stop by http://www.coloradofans.com there are different people that have had that problem. you can probably message them personally and see how they got to that problem. P0300= Random/ multiple cylinder misfire detected P0301= Misfire detected- cylinder #1 P0302= Misfire detected- cylinder #2 P0303= Misfire detected- cylinder #3 P0304= Misfire detected- cylinder #4 p0305= Misfire detected- cylinder #5 P.S. These are Diagnostic trouble codes, not vechicle id numbers.
I found the easiest way to do this is read the codes, if it is reading a misfire on one cylinder, then swap that coil pack with one of the other cylinders coil packs, then you will have to clear the codes and drive it, then see if it throws a new code on a different cylinder.
DTC P0128: Engine Coolant Temperature (ECT) below Thermostat regulating temperature; DTC P0303: Cylinder 3 misfire detected.....
P0420 Catalytic Converter is bad p1320 misfire P0305 - Cylinder 5 Five Misfire
the code p0304 is cylinder 4 misfire detected
p300 is a misfire
I'm not positive of the P0118 but i think it has to do with the engine coolant, but the P0306 is for cylinder 6 misfire.
Trouble code P0171 means: Fuel Trim System Lean (Bank 1) Trouble code P0300 means: Multiple Cylinder Misfire Detected
It has set a trouble code. Have the codes pulled at a autozone or oreilly auto parts.
I have heard this is a misfire on a given cylinder, but other things can cause this as well, so, pull and read the stored codes to assist. Any auto parts store, mechanic, or dealership can do this.
