This is for a 2009 Suzuki Swift+, 60,000kms
This morning when I started my car it idled really rough, to the point where it almost stalled and threw a P0303 code. I pulled the plugs and found that 3 out of the 4 cylinders where flooded. I put these other plugs in that I had (platinums for this make and model of car). After starting it again the idle was still rough. If I revved the engine to 2000 RPM it ran smooth. After a while the rough idle went away. I drop it on the highway for about 60km's without any issues. Stopped the car and it idled perfectly fine. No issues at all. I let the car sit for about 4 hours then went to start it again. It idled rough again (but was good at 2000 rpm).
Prior to driving it on the highway, I reset the code and it hasn't come back. Has anyone seen this before? According to the dealer the coil pack and plugs were changed at about 40,000kms as part of the recall for those parts.
