C32 gets 'tired'

Hi guys,

I'm new to the forums, and have been experiencing an issue with my car lately. It still accelerates like hell at first, but after one or two strong bursts, it's almost like it gets tired or something, and needs a few minutes to regain its power.

When driving on the highway, I'll be going along about 75 or 80, and every once in a while I'll feel a slight jolt, and the car takes more effort to keep at speed for a few minutes.

When these things happen, the throttle gets a little mushy and the rpms go higher than normal. The car goes back and forth between normal and weak, depending on how I push it.

Is this the classic I/C pump fail that everyone talks about? And when the pump does fail, does it show up as a malfunction on the dashboard computer display?

Thanks in advance for any insights.

Welcome!

Yes, your car's symptoms bear all the characteristics of a faulty intercooler pump. It's an easy fix.

No, failure of said pump will NOT elicit a warning notice on the MFD.

You're lucky if it lasted that long (Unless it's been replaced previously). Do you have any kind of warranty? If not, I wouldnt sweat it as you have a few options to replace it and fix the problem other than the dealership..

+10 .. Exact symptoms of failing I/C pump.. You can replace with the factory unit or upgrade to the Johnson CM030 approx ~$150. Then your car will be young and well rested.

Thanks everyone for the impressively quick responses. I had a feeling that was the case, and your replies are pretty much confirming my suspicions. I took it to my mechanic not too long ago, but it didn't throw a code.

Nice to see some fellow C32 fans here. It's an awesome car, and I can't wait to get it back in full force again.
