Hi Everyone,
I have QQ J11 1.5dCi Diesel. When it first starts the engine, it roughs idle when cold starts, and after a minute it settles down and back to normal RPM. The EGR has been serviced and cleaned but the issue persists. The mechanic has told me that it might be the fuel pressure sensor. Does anyone has had experience with the issue of rough idle when it first starts?
May I ask for your advice on how to go about this issue, please?
I look forward to hearing your feedback. Thank you
