Newbie owner - trouble already !!

Post by Judderman »

Hi everyone, bought my first rotary yesterday. 2004 RX8. Very excited - as you should be.

Test drove it a couple of days ago - all seemed fine.
Picked it up yesterday (from a private buyer) and within 5 mins the engine light came on - P2270 and P2096 codes.

I’m lookin for a list of relays - the ST relay under the bonnet fuse box is broken (plastic top smashed) so no idea what type it is to replace !!

Just trawling though the site for some help….

Anyhow. Previously owned an MR2 Turbo, and I’m hoping once I sort out the above stuff, I’ll have just as much fun in it.


:D

Hi and welcome.

I have just googled those codes and here are the results...
P2270
P2096

I am not an expert by any means, but I would check the O2 sensor in your exhaust. The way I work these out is to search both codes and then find something common to them both. In this case, the O2 sensor seems to be the common denominator. Could just need a good run if it's been standing for a while.
Good luck, there will be someone who knows more than me alone in no time to help. :thumright:

Could be as simple as a exhaust leak or a decat confusing the ecu. If you post a picture of the damaged relay (which could also be causing it) I’ll send you a replacement for the cost of postage

Hi and :welcome: Judderman. :D Hopefully you'll get your codes sorted quick and easy. When that's done - have a good read through whatever in the FAQ section you didn't already read :study: and then (and just ignore me if you know all this already) here are my best tips for keeping it all running sweetly:

1. To start up turn the key to position 2, wait for most of the lights on the dash to go out (I watch the airbag light by the glove box), press the clutch to the floor (optional, but reduces drag), turn the key to start and do not touch the throttle until it has started. You can drive off straight away, just keep the revs down for a bit (see #4 below).

2. Never [-X turn off the engine before it has reached at least somewhere towards normal operating temperature (should only take a minute or two, but best to go for a short drive if just swapping cars round on the drive etc). Switching off cold risks flooding, which is a real :censored: with a rotary engine. Mazda recommend rev to 4k and hold it for 8-10 seconds switching off while still revving if you have no option but to switch off cold (it is not necessary to do this in any other circumstance).

3. Check the oil level regularly (use the dipstick - the oil gauge tells you nothing other than that you have or don't have pressure) and top up if necessary with semi synthetic 5w30 (most people and specialists are advising to use 10w40 now though) ... small amounts at a time, no more than ½ a litre then check the level again before adding more as you don't want to overfill it.

4. Use all the revs once the engine is nice and warm (don't sit idling to warm up, start up and drive but keep it below about 4k until the needle on the water temperature gauge is pointing straight up, then give it another 10 minutes for the oil to warm up too before really thrashing it :twisted: ) and hit the beep often. Best acceleration is from 4k revs up - to pull away you really need to rev to 2k - you can let the revs drop after lifting the clutch if you are in traffic, cruising steadily at 3½k revs and changing down to go up hills or accelerate gets you the best mpg ... which still won't be great. ;)

5. Join the club for discounts on all sorts of things (you will very quickly get the cost of membership back - and then some), loads more info in the members only sections (including access to all the workshop and technical manuals), local meets (they were all postponed but are beginning to happen again now) - if you can't find one exactly local it is a good excuse for a drive if you come to one a bit further away), a sexy keyring just for joining and more. :thumright:

Good news! I think the RX8 makes a great project car, and there is plenty of information here and elsewhere on the net to help out. Don't believe the name sayers, these car are fantastic, if your a car guy/gal, if you just want a car you can drive and forget about, it's not for you! LOL
