I've spoken about this before on a previous thread. I apologise if some deem this thread unnecessary, but I'm at a loss and in need of support from the dedicated members of the Renault Forum.
Issue: When I accelerate, the car slightly judders. The rate of acceleration is poor during the judder. I have no option but to keep the gas pedal firmly to the floor to gain as much speed as I can. The acceleration normalizes when my revs are high (3000+).
Here are a few things I've noticed:
1) The problem starts approx 1 minute after starting the car.
2) The issue starts when the engine temp needle begins to rise.
3) The engine emits a ticking noise when the acceleration issue occurs.
4) The issue goes away after 3-4 minutes of driving (a minute after engine reaches operating temperature).
5) Important: The issue only occurs once a day. It's always on the first journey of the day.
The things I've done to try and resolve the issue:
1) Changed engine oil and oil filter.
2) Changed air and cabin filter.
3) Replaced spark plugs.
4) Sealed a cam cover bolt to stop oil seeping from under it (as advised on this forum to resolve the oil leak).
5) Cleaned throttle body.
6) Replaced upper intake manifold gaskets.
Possible culprits:
1) Faulty brake light switch.
2) Faulty pencil coil(s).
3) Faulty map sensor.
4) Blocked fuel filter.
5) Cracked cylinder wall.
6) Cracked hose(s).
7) Faulty coolant temp sensor.
8) Failing fuel pump.
9) Stuck thermostat.
10) Excessive wear on the duel mass fly wheel.
