Weirdness, Power Came back !
 

Well, I got the sCANalyser installed to my old laptop, ran it, and got the engine code out, but please read the whole thing

Car ran for maybe 10 mins :

i have no idea what most of them means, but the thing here is that ;

After I "got the DTC" stuff out of the CAr, I drove it around a little .... and after some huge *pole hole* (I missed and ran pass it)

BOOM BOOM !

hmm? ....

My car Acclerate again !

Like the old times, not 100% but I will say 95% !

AT first I dont believe it, then I try to rev it faster and yes it can go upto Redline !!!!

Of course, Engine light is still there, but my 8 "seems" to back to normal now.

The Error Code should be something

P0410 AIR system problem
U0155 Communication error to instrument cluster

I think my "Lack of power problem was related to the first error code", second one Im not sure what it means. instrument cluster? every gauge works on my car hmm .... maybe except for the Oil Pressure sensor or something, since it always stays a little bit pass to the middle to the right side (no matter if I add oil or not)

Dont know, very confusing now.

Do a search within the RX8Club forum for "P0410" (no quotes) and also do a Google search to see what this code can result from. Basically, check the AIR pump fuse, relay and check valve. If you don't know how to do that, get the service manual or take the car to a dealer for service.

The U0155 code may be related to a communication problem between your sCANalyser and the PCM.

Your Oil Pressure Gauge is basically not a gauge. It just tells you if you have oil pressure or not. It is deceiving in that regard because it looks like a gauge....if your car has enough oil pressure it will move to slightly pass the middle.

Nothing change,

Basicaly my car "lost" its power out of nowhere.

but after that "big bump" plus I was pushing it really hard.

all of the sudden it got its power back.

Probably something was stuck somewhere, and the thing "came out" after that bump + Push

Dealer told me to change it back to stock before they will fix it, I can understand why now because they see a "Air System Problem" kind of Error (they wont tell me before)

I dont believe in "change it back to stock will fix this" since day 1, and I guess Im right this time.

Anyway. Will search more and see what happens.
