Brand New EGR Valve Fitted and.....

the FLAT SPOT is still there.

What next........I give up!!

Why is this such a stupid problem...surely there must be a fix....surely someone has found a resolution. ITS ONLY between 1 - 2k rpm and after that its fine, and there are no other issues, and its been serviced and its had the airbox mod and its got an K&N Panel Filter!!!

Have you cleaned the boost sensor? Check the MAF too.

Yeah, the MAF potentially, but from your other pics, the inlet manifold had a tremendous amount of crud in there - could be that (again).... especially of when it was changed they fitted the older style one....

The inlet wasnt too dirty this time, just a bit of soot......which the carb cleaner soon sorted out. I even had the battery disconected this in the hope that it will reset something!

What do I need to do with the MAF?

The boost sensor has been cleaned also, will do it again! Any recommendations what to clean it with?

You get a spray from ebay http://cgi.ebay.co.uk/Mass-Air-Flow-...d=p3286.c0.m14

OK, so how exactly does that work? Also, if there is a problem with my MAF then how come no codes have flagged up?
