Please can somebody help?
I've spent a load already getting the car diagnosed (AMM & EGR) and the parts replaced. Initially, it seemed better after I put the new EGR on, however, after a quick blast, the MIL is back on on tickover and it also comes on if you rev it past around 3.5k with a noticeable drop in power. Switching it off and back on, it's fine until revving it to 3.5 again.
I don't really want to dish out another load of cash getting the code read again as the car is only worth a couple of hundred quid.
Is there anything I check and try before going down the diagnostic route?
Any help/suggestions appreciated.
