RX8 nightmares
Discussion
Hi guys, have you got any ideas what to try next ?
Just taken delivery of second hand Rx8. Ran fine for 10 miles. Then cut out at junction. Difficult to restart then lost power big time and got very hot (smoke out of handbreak apt.) AA diagnosed coil pack fault. Towed to Mazda independent noted specialists who has fitted 4 new coil packs,new plugs,new leads. Wanted to replace Cat but I declined as it had been replaced 4,500 miles ago & their cost was £900 so far ! They Checked compressions all good. All recalls done, High speed starter motor, New Battery, etc.
Ran ok after but Engine light still on. Fault code now - PO 302 - I Removed Lambda probe, looked fine, blew out with airline. Done 80 motorway miles today hoping it might clear cat out but it cut out at lights twice and struggled to restart. Doesn't seem to rev as freely as remember they do either. Should I bite the bullet and fit new cat & lambda or is it worth Gutting the cat ?

Thanks for reply folks. Genuine cat fitted. Also noted genuine cat fitted by main agent when car had only done 4,000 miles from new! Now 88k. Had car connected to gas analiser at MOT station yesterday, showed MOT pass results good. Still easy to stall at junctions and a real pain to restart when hot using standard factory methods. I believe you can trick system by jiggling Fuel Fuse or Fuel pump connection when start problem occurs but this is a big problem when you're holding up the traffic. Do you think it would be worth/safe, connecting remote switch with relay to the fuel fuse so could be controlled from drivers seat. I'm being told, when these rotarys give problems like this they can never be fixed without new engines ! Mine does not use oil or blow out smoke. Pulling my hair out !
Yes. Compressions taken when hot. Having just spoken to the Mazda specialist who carried out last weeks work for me. They reiterated, my compressions are good. They had turned down minor work yesterday on an RX8 with compressions around 5 & just under.
Have you any thoughts on cleaning/replacing internal EGR valve ? This is a Renesis 2005/54 plate, I believe they don't have an external EGR ?
