trouble codes 3!!!
 

First off yesterday i was driving.. and in first gear only around 5.5-6.5 K rpms the car would jerk.. never happened before..

power seemed ok... check engine like comes on (solid light)

and keep jerking but only feel it in 1st gear..

Today i wake up check all my fluids.. oil coolant, Etc..

soo i start driving and yesterday i re set the ecu by unplugging the batt and it ran fine..

this morning (continuing) it jerked a lot in that range and my power went DOWN! i didnt have any power.. and check engine light came on again..

codees are


p2004
p0039
p2070

any info would be helpful

Ahh found out what some of them are...

SSV stuck open???

and the other one is APV stuck open???


how in the heck would that happen?

carbon build up.. drive it hard..

could it be carbon build up?????

i mean ai always use supreme Gas...
I always use fuel injector cleaner (lucas)

Sea foam. Oil changes at 3K miles.. its well maintained.. I dont granny shift i shift usually around 5K rpm..

Sometimes at 6K rpms

I rev it up everyday..

Could be carbon, but if both codes happened at the same time (was the check engine light off before this problem happened?) it's most likely a wiring problem, or a PCM malfunction IMO. The former is more likely, and will be hard to diagnose... the latter will be expensive. If you don't know your way around a volt meter and a wiring diagram, take it to a shop that knows a bit about RX8s or a dealership that you trust and have them look at it.

Also, are you certain about code P0039? That code isn't even mentioned in the service manual :uhh:

idk thats what came up lol. hahah


Well the first code that came up was p2070 and i reset the ECu and it camer back on...
re set again

And this morning the ligth came back on..

and instead of p2070

it threw the code p2004
