Leading evidence: 'spark plugs' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'spark plugs' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check light came' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

It has been in again since for the loss of oil pressure which was a crank shaft seal repaired under warranty but i think they only replaced it as they had the gear box out a few weeks before to replace the fly wheel and clutch and more than likely caused the damage

My 98 c2, had a missfire and the check light came on, but then went off, the fault was still logged though.

I would have thought the engine check light would come on if the fault was logged as a missfire.

maybe using a rolling road would help identify it.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

my car has just started to feel lumpy on tickover and also seems to miss when you are holding the revs up around 5,000 and on a few occasions after pulling away from stop it would not rev over 3k anyone got any ideas it is booked in to the dealer in 10 days time just hope i dont get another huge bill
the car is a 2003 996 c4s

Take it to a good indie close by - it should be a straight forward fix. Could be something as simple as a ignition lead breaking down. Whatever you do, don't drive the car until it's fixed though!

just collected the car from opc but they said they have pluggged it in and there are no problems who knows maybe it is me

I had similar problems on my two previous Nissan Skylines, missfire at high revs.
Cause was failing spark plug. You should get it looked at (again) as this missing could cause more damage.

if the miss doesn't log a fault in the engine management then they won't find anything.
I would have thought the engine check light would come on if the fault was logged as a missfire.

it's back they said there was no fault showing but you know your car it seems to be ticking over lumpy but bournemourh opc told me this is correct and i think it is holding back after 5000 rpm. It has been in again since for the loss of oil pressure which was a crank shaft seal repaired under warranty but i think they only replaced it as they had the gear box out a few weeks before to replace the fly wheel and clutch and more than likely caused the damage
