Hi,

Has anyone had issues with rev's dropping when pressing on the accelerator?

Started about a week ago

When the engine is cold, happens over all gears

When I accelerate, car starts pulling then briefly the revs drop and that carries on as normal.

My mechanic has looked at it already. Engine management light has not come and when idle, rev okay.

Any help would be good,

Thanks

Hmm, only seen this when idle with the revs dropping. The only thing I can think of is the MAF sensor.. but it's unlikely. Worth trying it anyway. It's a small black sensor that is attached to the tube coming away from the airbox. Has a connector on it. Disconnect and pull out the sensor. Clean it in some solvent such as brake cleaner.

Hi JeoyJoe,

I've tried cleaning the MAF sensor but didn't help.

After speaking to a few people, starting think either something to do with feul delivery, also don't want to rule out the clutch completely, although I don't think it's that as I had it replaced a couple of years ago and when the went the sypmtoms were diffirent
