Gas Smell In Cab On Startup And Rough Idle On 4.6L
I own a 2004 (new shape) F150 4.6l XLT.
So far I have:
- Cleaned the MAF with MAF Cleaner,
- Cleaned the Throttle Body with TB Cleaner,
- Cleaned AiRaid air filter,
- Changed all plugs,
- Changed all coil boots and replaced coil #1 which had a broke clip.
However, I am still experiencing a very rough idle when in Neutral or Park, no matter what temperature the engine is at. In addition, I quite often experience a strong smell of gas in the cab at startup.
I have purchased an OBDLink MX OBD adaptor and installed both ForScan and Torque Pro. I am very new to OBD diagnostics so would appreciate some help and advice on how to read the results and what graphs to create.
Below are my Torque Pro Mode $06 test results. There are a couple items which have failed and a couple of very small count misfires (cylinder #4 and #7). Would this be enough misfires to cause such a poor idle?
