Hi all when my engine is hot and I switch the engine off for 5 minutes or 3 hours I start it up and it gos slow till I got pass 3 thousand revs then it's fine do any one know why it gos slow but when engine is cold it's fine. I unplug the Maf and it still do it
 
Only a live data log would be relevant here...might be fuel temp sensor erratic signal(the one in the FPR) if you dont have access to nanocom just replace it with a bosch one cos it's not expensive(e.g. http://www.ebay.co.uk/itm/BOSCH-028...CU-/131793190234?_trksid=p2141725.m3641.l6368 ) though the crank sensor can make tricks as well but this one is expensive just to replace it based only on suppositions cos there could be many other issues too...do you still have EGR?
