Cel and cruise main light
 

I have a 2004 RX8, and when I replaced the battery my cel and cruise main light came on, it idles at 2500 rpm, and when I give it gas, I get no response. What do I do. Need help please....

get the cel read.

I'm not sure my DLC is working properly

Hard to imagine just changing the battery brought this on. What else did you do?
Are you sure your connections are clean and tight? Did you forget one of the wires on either the positive or negative side?
Did you hook it up backwards..even for a brief second?
I get the feelilng there is something else you aren't telling us. :dunno:

Did you do they TCS/DCS reset? You should have had to do at least this reset if you had the battery disconnected for any length of time, but you didn't mention it. this is not your problem, but is curious that you left this out of what you wrote.

No, really.... All I did was replace the battery, i did put new connectors on, but hooked up positive, negative properly. I tried the 20 pump brake in 8 seconds, and the cruise light will not go off, and push gas pedal to floor, nothing.

I did the TCS/DCS reset

Well, the 20 brake pedal stomp shouldn't effect the cruise anyway.
When you did the 20 pedal stomp, did you oil gauge sweep to the right and then back to the left? I still don't think this is your problem, but would be interested to know if the gauge did sweep. If not, you might try it again until it does. This still isn't your issue though................and I'm still thinking!

This is a weird one, which usually means something was overlooked or it's really, really easy.
I know, I know, but that usually is what it indicates.

check those negative connections again.............make sure they are good and tight while I think of what else it could be. You don't have any starting issue right? It just idles high and throttle does NADA?

Have you tried hitting the cruise button on your wheel? Since my last flash the stupid cruise system will stay on even after shutting off the car.

^.......really.............that's F'd up!

*shrug* I don't think much about it really. It doesn't remember the speed it was last set at, which I guess would be somewhat handy, so I just drive around with one less button push to get my cruise to work.

I believe my VIN# is before the oil pressure guage moving on the 20 brake stomp, Im not to concerned about the cruise main light, I just want it to go when I give it gas. It has no problem starting.

Press gas pedal....nothing
 

2004, idles at 3000rpm, give it gas, no response, cranks up no problem, just won't go....

Still thinking....................what about TPS(Throttle Positioning Sensor)?

I have not checked the TPS, it is an automatic, where is it located...

Rtalbert - did you find an answer to this problem? Can you update this thread? Was it a problem with your OMP (oil metering pump)?

some wat same sitch on my car my main cruise light turned on yesterday why idk how do i turn it off idk ( any help)????
but it might be your cel bro cause my car runs fine and its an automatic as well

wat same sitch

Sorry, not prepared to expend the effort to parse this "sentence".


Fail.

sitch = sitaution my apoligies any info on how to turn it off?

To the original poster, all sounds related to your thottle body/drive by wire assembly. Could be stuck in "fault mode". No throttle response, no cruise, high idle.

I'm going off the top of my head here, but I think if you pull of the intake boot and turn the key on an leave it on, the throttle blade is supposed to do a self check/sweep and relearn the position? Peek in there and check it. Just don't stick your fingers in there. Someone have a workshop manual handy?
