can u advise at all whats wrong as the garage are even baffled with it now and are saying its maybe my tips need replacing

its an 06 model btw

 

Have you had the code read?
Coils and plugs should be checked and changed at the same time, as the breakdown of one will affect the other.
First thing to do is get the CEL code read!

 

its been read numerous times the original fault was p0301 on the invoice i hav,as for this new reoccurring fault he just told me its the random misfire code.. not sure if that is the same code
think it is tho

 

Check to make sure all of your leads, coils and wires are seated properly.
Most likely, it is a failing/failed coil. You can check those with a coil tester. Or, you can purchase 4 new coils and install.

 

Plugs,wires,coils. and check how the plugs are wired. it should look like this:

i am not gud with cars at all usualy send to garage are they easy to do yourself?



was thinking coils tbh but as they cost £75 each over in the UK(what i was charged)was leaving and hoping it wasnt that

 

as i hav no idea whereabouts are they on the engine? underneath around the back? sorry i hav no clue :/


looks like on the right side as lookin at engine on that pic,that it?

 

yes, looking at the engine, the coils are to the right. Follow the wires to the leads.

^Many people get that feeling.
The RX8 is like a guy/girl relationship- if you don't respect/understand it's wants and needs, tempers flare and the door may hit ones *** on the way out

 

just make sure plugs are seated properly as well. and don't give up on the car it just needs a little more work then piston engines but other then that they are awesome.
