Help
I have the MG ZT CDTI 05 (90000 on the clock) remapped to 160 bh.
Before and after the re map I have noticed that the revs take a long time to drop from above 2500 rpm when the engine is hot, the higher the revs the slower it takes the engine to drop to a level where it is comfortable to change gear. Could this be an air leak?.
This is my first diesel so not sure if this is a diesel thing and just have to live with it
I have changed the "O" rings in the inter-cooler, bypassed the EGR, changed the PCV filter, had a full service on the car (air + fuel + oil filters changed). The car accelerates very well with little white smoke. I have even had the ECU checked which returned 3 issues
1. accelerator peddle issue (seems ok and very responsive)
2. Low pressure on the fuel rail system (both fuel pumps are ok)
3. unknown error
I have ordered a new MAF just in case but as stated the car pulls very well form about 1300 rpm
Any help would be appreciated
Thank you
