Hi everyone.
Since owning my car for just over year now it has suffered from jerky and uneven acceleration between 1500 - 2200rpm (After that its smooth all the way up to the redline). The symptoms are much worse when the engine is cold and does improve once it has warmed up but still remains. It is mostly noticeable in the lower gears. No EML to date and no fault codes stored in the ECU.
The car has full service history and I've recently changed the air filter, oil and filter and also the spark plugs. It made no difference. I have also cleaned the throttle body, changed the VVT solenoid including the gauze filter and also the crankshaft sensor yet the fault persists.
Does anyone have any idea or advice on what try next?
