Highs and Lows of the day I got my Rex!

Having read through this thread, I would suggest you get someone who knows about rotaries to have a look before you get into full blown doom and gloom, it could be something as simple as a plug lead that has come off in fact it could be a number of things.
Bearing in mind Donnato must have driven her down from Scotland and that it had just been compression tested and knowing Pips maps are quite conservative I would be quite shocked if it is a tip failure.
As stated by the others I take my hat of to you on your attitude.:cool Best of luck with her you have a very good car there.

Your right - there’s always a chance.  I\'m going to take millspeed up on his offer and give him a call later.  It\'s always worth having someone who knows what they are looking for!  As I said, one of my mates is going to speak to a friend who is an ex mazda technician and ask him to have a look.

Again - thanks everyone for the support! :wave

check the boost hoses under the plenum - they can cause the bad idle and irratic boost readings ( from what i have read )

you can always compression test it using a normal compression tester - this will give you a good idea aswell

Dont even need a comp tester - Take out the EGI fuse, remove lower rear plug and turn her over you should get 3 even whooshes of air, put the plug and lead back on, remove lower front plug, repeat the turn over, if you get any uneven whooshes [1 good one followed by 1 or 2 poor ones] this will indicate poor compression [dont forget to put the egi fuse back!]. As the car has been converted to run non-seq. a great deal of the \'rats nest\' will have been removed so it should be quite easy to trace the hoses.

[grinder]

i was gonna suggest that - but i thought the comp tester gives a visual indication rather than guessing the number of WHOOOOSHES !

still a poor mans way of testing it though

hmmm I dont think the engine has popped. I reckon the fault lies with the MAP sensor myself or one of the plugs has gone, get it to rotary specialist.

Black smoke indicates a very rich mixture which all points to the map sensor. When I have thrown a tip/seal in the past the symptoms were slightly different, no smoke as such and difficult to start with a weak idle, but would drive fine past 3000 rpm

Im sure is something simple matey, fingers crossed for ya

I do hope your right.  During the drive - at wot the air/fuel guage did show it move towards to richer side.  Even when it all went tits up, the guage showed the same levels as before.

As posted before - I will give millspeed a call and see if he can see anything simple.  I tried to get at the plugs to check yesterday, but it looks a bit awkward.  I\'ll give it another attempt later.

I\'m not sure who the closest rotary specialist to me is (Swansea) so I may have to hire a trailor and get it to one.

In the West you have Ross at Dragon (Exeter) or Tim at RX Motors in Blandford Forum in Dorset.

I don\'t remember having loads of black smoke when I threw a tip (or two!), just a really lumpy idle (wouldn\'t hold idle without a bit of throttle) and an absolute pig to start! also ran with half the power it should have had as I ended up running on one rotor!

I\'m trying very not not to get my hopes up - but after a lot of these posts its getting pretty hard :p

As I said, when I have tried to start the car it has worked first time and it doesn’t need throttle.  The power loss was terrible though!!  I don’t know if anyone has ever been from Abergavenny to Merthyr and seen how steep the hills are - I struggled up there at no more than 25-30mph.  That was easily the worst part of the journey.

Hard to say at the minute - but at the moment I\'ll be quietly cautious and not expect miracles.  It will be easier to deal with if a full rebuild is then required

could well be a manifold leak or map sensor.

Aww man !

Gutted for you - I really really hope its something incredibly simple.
With all the expertise offered by this forum and its members I\'m sure it will be an easy fix ! (fingers crossed)
It was nice to meet you at WGT - and if Pip gave the car a clean bill of health then it must just be down to luck - bad luck - but luck just the same.

Heres hoping it\'s nowt major.

Unlucky mate, I\'m impressed with how your handling this I don\'t think I\'d be the same.

Hope its a simple fix.

Closest to you i think is Dragon performance in Exeter, or possibly Hayward rotary ?

Both have links at top of page cheers,

Hats off to you mate, just remember to keep the feeling of that 3rd gear boost in mind while its off the road! :yes

The symptons sound like the MAP sensor so much, hope it goes well for you.
