Hey guys,
I just bought up a rx8..... Been few months now did servicing and spark plug change on it..... But I don't know why the engine cuts off when I use A/C and it's kinda been a little bit fussy when I try to start it up.... I am from Fiji so any idea what's wrong? It also makes it difficult to start when engine is hot and sometimes late start when cold

 

What's the history of the car? Year, kilometers, previous problems? I don't suppose you had a compression test before buying?

 

I am the second owner of the car.... It's a 2004 type s spec rx8 and has done 106000kms..... The car was not used for 3 years since the owner had migrated.....but I really can't find what's wrong with it. The engine just cuts off when I use A/C and it starts late when hot

 

Those are signs of compression loss, but it could be a few other things as well: aftermarket intake, vacuum leak, failing ignition coils.
