Be more descriptive in posts.
How long have you owned it? Do you know its repair and maintenance history? Is it turbocharged or not? Do you have a CEL? Can you check for codes? There are many inexpensive code readers available. You should get one. If your plugs are old + neglected, replacement is a good option. However, inspection of coils is involved without knowledge. A misfire on one particular cylinder is helpful and likely recorded by the ECU with a code. Reading a code is way smarter a first step than buying parts without intel. P0300 is that of a random misfire. P0301 to P0305 specifies the cylinder. |
