500 miles on rebuild and... Injectors?

jeudi 2 mars 2017

I recently picked up my rx8 from the shop after having the engine rebuilt. As far as i know everything was reused except the Housings and seals obviously.

I have just passed 500 miles on the break in and I'm starting to do pulls passed 8k. It seems like the engine cuts out at anywhere between 4k and 6k rpms sometimes higher. Its a short cut but its extremely noticeable. Im trying to remember correctly what the mechanic said pretty sure it was something along the lines of the secondary injectors not being used much and that it would clear itself out eventually. I've also been premixing pretty heavy at their recommendation of an ounce per gallon of marine 2 stroke.

So my question should i look into new injectors? could it be the premix creating the problem? Or are there any other possibilities? I did notice the exhaust sound almost seemed to becoming more from the middle of the car. I had them check the cat and he said it was fine but pretty close to its last leg. Could a clogged or partially clogged cat be to blame as well?
