Horrid Hesitation

[c928jon]

Hi,

I've owned my 99 996 C2 manual for about six months now and had my share of the usual problems, RMS, coolant header tank etc.

Recently the car has seemed to loose power intermittently and no fault codes are stored anywhere! I'd had a fault with the alarm that required the battery disonnecting and had assumed the computer was re learning positions etc. I've done about 1500 miles since it was last disconnected and unless it has serious learning difficulties I guess it's something else!

The car will either rev all the way through the range without hesitation but seems to be retarded or pull like a train then hang for a split second before continuing.

This isn't a variocam stutter, on Saturday, whilst entertaining a spirited encounter with a integra type R it actually hung at 6000rpm as though a limiter was fitted!

I have a bad smell of burning oil after a high reving excursion and although I may have imagined it I thought I saw a puff of white smoke just after the engine hesitated.

It doesn't seem to exhibit a problem during warm up but of course i'm not pushing the motor!

Any light that could be shed on this before I utilise my local garage for hugely expensive diagnostics would be much appreciated.

John
