[spidy-RX]

hallo guys,

i got a big problem with my FC.

yesterday on the autobahn the car starts to move badly when i pulled the gas. ... on the next exit i stopped it and on idling the enige died off.

after many many many crankings ... the FC starts again... but ->

look @ youtubevideo

but no smoke, water is ok ... ?!? all hoses on the correkt places.

-> time to rebuild?

is the car doing that on its own?

or are you using the throttle to keep it going?

[Brett]

Can\'t view the link at work.

Have you double and tripple checked all of the hoses after the air flow meter?  
What sort of driving did you do prior to it going wrong?

[spidy-RX]

no i´m keeping on gas under 1000rpm ... otherwise the engine dies off

now i moved the idling to 2000rpm - its holding it.

yesterday i was filling in gasoline (100oktan) and moved on the autobahn... pushin a little bit to 160km/h (not over 5000rpm)... then let it down to 130 km/h.

then i want to hold the speed - throttling a little bit -> car starts to shake and dont want to take the gas correctly

-- sorry 4 my bad english.

Could it be related to the TPS?

[Prof]

I did wonder if it was TPS - but if it\'s not holding an idle below 1000 RPM, then it does sound like engine problems (compression).
 
What\'s it like to start - is it hard to start or easy ?
 
Try taking out the bottom spark plugs and the EGI fuse, and crank the engine - you should hear 3 strong even whoosh sounds - do front and then back of the engine - so you hear the noise from each rotor in turn.  If that sounds ok then try looking at the fuel relay at the front of the car, and also do a check for error codes - it might have gone into limp mode.

its very hard to start

i´m looking for a comression tester at a local mazda dealer. if there isn´t one. i´m goint to test it like you told me.

but it seems like a engine breakdown

Make sure you have no vac leaks at all and that the map sensor is plugged in and no broken wires. Think you need to check all the basics first, spark( I would change the plugs), fuel and then vac hoses etc. Make sure you intercooler clamps are on ok as mine did something similar and it was one of the hoses i had forgotten to tighten.
Just make sure the ECU is ok as well,not waterlogged or damp. Been dry lately over here but not sure on your weather at present.
as a basic test just pull the plugs and turn it over(pull the EGI fuse) and hear the wooshes from the plug holes, that might give you an idea of how strong they are.

2 ECUs checked. same .....

tomorrow i´m going to check the the "wooshes" (recording by my LG secret)
