Hi guys. I have a 2004 AT rx8 with 130,000 original miles and about 70,000 on the engine. I live in texas and havent had any problems at all with the car until its started to get hot here lately.

Sometimes when it has been running for a while, my car will die if the A/C is on.

I just replaced my wires, coils, and plugs today and its still doing it.
Also when i went to change my spark plugs out, the old trailing plugs were a different type than the leading ones,they were both ngk but the sparking ends were different.

Also suprisingly, the leading plugs were in the trailing holes, and the trailing plugs were in the leading holes. i cant believe the last owner put these in wrong when theres a big T and L on the side of the engine.

any ideas would be great thanks!

 

Have you checked the catalytic converter? It might be clogged...

 

hmm.... no i havent how would i check for that is there a way to test it?

 

Just take off the catalytic converter under your car or have a certified mechanic do it for you, and visually check it, or try to read this, this could be related to your issues your having as well...
