Change the coil. Period. Very easy to remove from the vehicle if it's a 4 cyl. Follow that spark plug wire from the spark plug to the other end. What it's attached to you should replace.
try changing the cap and rotor
It means that more than one cylinder has a misfire history. PO301 would be cylinder number 1 misfire. PO302 would be number 3 cylinder misfire.
po300-Random/multiple cylinder misfire detected. po303-Cylinder no. 3 misfire detected. po306-cylinder no. 6 misfire detected po300-Random/multiple cylinder misfire detected. po303-Cylinder no. 3 misfire detected. po306-cylinder no. 6 misfire detected
Cylinder #4 misfireCylinder #4 misfire
p0300 is a multi-cylinder misfire code it is because the logic circuit cannot determine which cylinders because they are random
How is your coil pack ?
Cylinder #2 misfire.Cylinder #2 misfire.
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.
Random misfire, cylinder 2 misfire, and cylinder 3 misfire. see related question below.
