87 944 turbo, lack of power for 2-3 secs?
 

Hi, I hope somebody might have a few suggestions; recently my car has started losing power for 2-3 seconds then its o.k. again for the rest of journey.

Im noticing this is normally within the first 10-15 mins of driving.
The car doesn’t actually stall just loses power then picks up again (this isn’t on a boost, just normal driving)

The cars always serviced when due and in the last year I’ve changed the recirculating/dump valve, ECU, DME relay, fuel filter, coil etc.

The leads look fine, used injector cleaner I’ve even replaced the DME relay again however problem is still there.

Im wondering what else might cause this, maybe something on the fuel rail/pump?

Does anybody have any idea of what could be doing this? Please help
