Power dip
 

Hello,

This weeekend I took the car into the track and afer several laps of great fun I started to feel a strange behaviour. After shifting one gear up and being back on the throttle, the car didn't gave me any power during half a second, like there was no gas or spark. This only happened sometimes, and I remember to happen more after a second gear left turn where the exit is uphill. I don't think this is the problem, but it happen more there.

Also it have happened to me that on a traffic jam if I'm hard on the throttle on low revs the engine hesitates and jerks a little.

The car mounts an Ingen CAI.

What do you think it can be?

Possibly lugging the engine? What RPM range are you in when you are "hard on the throttle?"


Thanks!

Just above iddle. It's not that the engine jerks because it is too low on revs. The problem is that there is no power at all (like no fuel), if I release the gas pedal and back again the engine responds as expected. Until now I have had only this problem on low revs in traffic, but now I've seen this also on high revs on the track.

It looks like the ECU does not calculate properly for high throttle changes or there is a problem with the throttle sensor maybe.
