Hi was wondering if anyone could help me my rx8 struggles to start then dies at idle unless I keep revs up have oil In the air intake pipe I checked the cat all seems to be fine checked the plugs with spark plug tester seemed fine to me checked pipes for vacuum leaks cant find any wondering if anyone could help me please??

 

Are you able to upload a video to youtube so we can see what you are talking about? And does it do this all the time or only when the car is warm? Did you clean the MAF with MAF cleaner, and the ESS sensor? How long has this issue existed, how long have you owned the car, when was the last time you replaced the ignition coils, wires, spark plugs? We need a lot more information.

 

Hi I will upload a video tommro started a few weeks ago and it does it all the time no I haven't cleaned them I will do that tommrow to i haven't replaced the plugs leads or coils but i have tested them and seem fine thanks for the reply

 

that is the link to the video sounds loud as I removed cat to see that was blocked just cleaned both sensors made no difference

 

Its very hard to diagnose a car over the internet, but that motor sounds pretty screwed.

Get a compression test

 

Why does it sound like you have one spark plug removed?

 

Not sure I dont I have removed the cat that's all

 

Little update I put the cat back on and its alot worse harder to start smells of fuel sounds like ***** and dies straight away

 

Sound like cat could be plugged. Did you see anything missing or broke inside. It could have broke a piece off and got stuck further down the exhaust restricting flow.

 

I can't hear videos at work but my car blew a rotor and it sounded like a truck when running or aka with out a spark plug and would blow lots of smoke when you got on it. are you able to rev it in (N) and does it blow smoke? From what it seems like it might be the engine but mine was still able to rev to what ever just sounded off and didn't run good. So I would definitely look into the cat and see if it's clogged or not and if you're really worried about it you could take a bar or something with the cat all the way off and bash thought it. You'll get a check engine light but it will help the car run so much better if it's clogged

 

The cat could be clogged, before bashing it out I would shine a light through the front and then look through the oxygen sensor hole to see if the back half of the cat is damaged...

That said, the motor sounds like its blown in my opinion.

Check out my video of a Rx8 catalytic that looked good from the front, but looking through the oxygen sensor hole told a very different story.

 

Thanks guys I will check the cat tommro also I'm over 100 miles from a rotary garage is there any other way of finding out if it needs a rebuild?

 

If you have a rotary shop that can do a compression test it would be best to get there sooner then later. Cause if it is losing compression and you keep pushing it, you could end up doing more damage and if its not losing compression then they could surly find the prob so you can fix it or they could fix it for you
