Electrical problem?

Post by Jason9994 » Tue Apr 29, 2014 7:41 pm

Hey all,
Sorry If I'm posting on the wrong part of the forum but I've got a massive problem.
I've recently purchased my Grey 2008 Mazda RX-8 40th anniversary roughly about 2 months ago and The current km on the odometer is 96,xxxkm.
Last week Thursday I tried to get a Python alarm system installed in my car through Chadstone Autobarn, but they've failed installing the alarm because of the ECU being Cambus. They put "everything back together" and since that day, everything went haywire. First, the Engine light decided to flash and while I was on the freeway I wasn't able to accelerate so i got my car Towed to Chadstone autobarn. The next day Autobarn checked the wires that the installer had touched and 'fixed' the flashing engine light. Then the car went to safe mode and you can hear the engine choking real bad, and so we changed the spark plugs(Purchased from Repco Re9b-T & Re7c-L), but still that did not fix the problem. Autobarn checked underneath the car and saw that the o2 sensor was gone and the cat needed to be replaced.
So today I went to a exhaust place to get a new cat and 2 new o2 Sensors but that did not fix the problem. When the exhaust place started the car the sound sounded normal for a few seconds, until he attempted to Rev the engine. It still wouldn't want to accelerate and the smell of what was coming out of the exhaust was almost like it was just pure petrol. The exhaust place turned off the car and checked the bonnet and there was steam coming near the area where you check the oil, so they checked underneath the car but saw no sign of the problem. (The o2 sensor are Genuine brand)
My question is, what could the problem be? Could the cause of all of this be the cambus ?
Please help me A.S.A.P thanks all.

Because it has Remote start, which is what I need. If it's a misfire, would that mean its just wear and tear thing? or ?

if you read the thread I linked it could be anywhere from replacing ignition parts to a rebuild.
why do you need remote start ?

It helps when I need to go to work. I can warm up the engine before i go to work ( 5 minutes before i leave).

I hope its not to rebuild.. just got it ..

Are you getting any kind of CEL? I'd be inclined to take it to either a dealer or a rotary specialist.

The only rotatory specialist I know in Melbourne are in Thomas Town, which is opposite of where I am, and getting it tow trucked to that area would cost $$$$$ and that's something I don't have at the moment.

Tim's is on our side of town (I'm assuming you're near chadstone) but down in Frankston. Better than Thomastown.

Remote start on an RX8 is very complicated. I vaguely remember someone here (on the .au forum) saying they had remote start, I really wanted to ask just how they did it because from I can make out from the stuff I've read, the key needs to be within range of the key chip reader before the ECU will let the starter crank. The electrical system wiring is also somewhat weird in that there is actually 2 separate ignition power lines from the ignition running to various system, so if only one is powered you will have power to things like the back up light, keyless control module (central locking) and instrument cluster, but things like the accessories radio, cig plug, power mirrors, windows and HVAC won't be powered (or Vise Versa).

If you can get ahold of a OBD2 code reader and get the "Pxxxx" code, it will help a lot to see just why the CEL came up. I would also recommend Tim, I live close to Thomastown and right now my car is sitting in Tims shop having the engine rebuilt (albeit slowly lol). I should be down Frankston tomorrow sometime and wouldn't mind having a look to to see what wires etc have been cut into, and may be able to assist in patching it back up (if need be).

Well I brought my car to a mates workshop and done a diagnostic test and found out there was a fault which is something to do with the abs circuit? anyways, he ended up correcting it and its showing up as no faults.. But when I start the car it still feels like its not running properlly? like when you start the engine and you press the accelerator, steam comes out from what I believe is the fuel line.. Could this be because I've been using shell 98? I heard alot of cars are disappearing from our roads because of shell 98...

Lol no there is nothing wrong with shell 98. From the sounds of it your car just had the hardest week of its life. I dare say your plugs are shot again and it if they are your coils are likely fried and you probably need a good decarb. All that unburned fuel isn't healthy.

Ok update.. The mechanic checked coils, spark plugs, and they're all good. they tried draining the fuel but its not the case. when I replaced the cat i also had to replace the catalytic converter, and it heats up alot even when the car is on for a few seconds. the exhaust place got the o2 sensors from burson, and I was wondering could the wrong o2 sensor be the cause? or maybe its the catalytic converter... since the catalytic converter is different, it could be causing the car to not function properlly? any ideas anyone?

cat - catalytic converter are the same thing.
There is an air pump which pumps air into the exhaust to heat it up on initial start up.

It could, do you know what brand the cat is ?
In your first post you said the sensors where genuine so they should be fine.

Do you currently have the check engine light illuminated on the dash ?
Do you know what the code was that your mate got when diagnosing the car ?
