Hi all,
My Clio 197 has been running lumpy for quite some time now. Did the following but no luck getting it back on power like it used to be. My issue is the car was running lumpy on low rev, for example, I had to rev it a little while letting the clutch off to prevent the car from dying when the traffic lights turned green. I haven't really noticed anything on high rev as I do loads of city drive mostly start-stop kind of drive on low rev (less than 3.5k RPM).
I got the car diagnosed by a Renault Specialist in Dublin and got a bill of 1.5k euro saying it was the dephaser pulley that was causing the problem and they needed to replace the dephaser, cambelt, water pump, aux belt, coolant etc to get it fix. This is not a small money and I doubted it was the dephaser causing the problem as I hear no noise and the cambelt was changed 10k ago by previous owner (not sure if the dephaser was changed).
Just wondering if anyone has faced the same issue like mine what you did do to fix the issue? Below is what I have done and checked so far but no luck finding the issue.
Things I have replaced so far:
- Crankshaft sensor (old one previously caused a starting issue as it was coated with loads of carbon, took it out cleaned it and the car starts normally but decided to put in a new one now.)
- Camshaft sensor (the resistance of the old one is off by a lot and voltage doesn't drop when a piece of metal is approaching, put in a new one and the voltage drops as metal approaches - I honestly thought this will fix the problem but unfortunately it is not).
- Changed the engine oil (the previous oil ran for less than 1000 km but it smells like petrol, I think it was because the engine is running lean and misfiring as I am hearing pop and bangs outta exhaust!)
- Changed all 4 pencil coils.
- Took the injectors out and cleaned them. Also, poured in a bottle of cleaner to clean the valves, pistons etc.
Things I have checked so far:
- Dephaser solenoid (the one right beside the fourth cylinder counting from flywheel/gearbox) is working ok, took it out, cleaned and tested it, working alright.
- Sprayed brake cleaner around the engine while the car was running and heard no sudden rev so no vacuum leaks.
Many thanks,
Heng
