Hi there, please can you help? I have a 2005 231bhp Rx8 thats not running properly. It is displaying fault code PO410, and the car will not rev, little better when cold but really struggles to get over 2000 rpm.Just coughs and splutters. Its not smoking or making any terrible noises. Took it to someone in Mazda , he says hes checked the coils and also changed the MAF sensor, but no difference. Hes suggesting a compression test as he thinks the engine is U/S but it ticks over fine, just wont rev. Any suggestions please? many thanks ken

You will fined its the fuel pump the car will stop reing soon and it could flood if not up to temp ,,, i had this prob my self was told its the pedal sensor , mazda check
it and said its the fuel pump not getting feul to the Engine,, u- tube it you will get a viral come up an rx8 running bad , you will fined pump access under rear pass seat to top of tank
