Really need advises for my 997.1 with IMS problem.

Recommended Posts


I am seeking for some help on my 997.1 C2S (2005). 2 months ago, when I was driving my car in the city (low speed), after turning round the corner suddently all dash lights came on and followed by engine cut off. As there was no particular weir noise beforehand, so normal response I turned the key and the engine started but only for 2 seconds before it cut off again.

From there, I realized that the rear floor was full of engine oil. The car of course ended up at my mechanic with engine off the car noticing that the IMS bearing was broken inside the housing but no visual damage seem to appear on the IMS itself.

Anyway, to cut short I had the ims bearing replaced with taking the whole engine apart. After the repair I took the car for test drive, it seems running fine but when engine is cold, everytime I accelerate from zero, the throttle response feels a bit shakey and doesnt want to accelerate. However once the car has been warmed up, it is back to normal.

Can someone please advise me what might be wrong with my car? Will it be sensor issue? It has only done 45,000km.

Sorry to hear about your experience Eso. It sound like you're experiencing some hesitation which could be caused by a number of things. Is there a check engine light on or are any codes present?

Thx for yr reply. No warning light at all so far. Am trying to get a full diagnostic done soonest to see. What's yr advise?

Make sure the diagnostic includes a scan of any pending codes in the computer. That will show whether there is a problem about to manifest its self. Seeing as how the hesitation didn’t appear to be present prior to the IMS problem my guess would be your problem is electronic/sensor related in nature.
