Hello!
It was an air host under the throttle house but now i have mooooore problems.
I have no luck with this car, still i love it!

so I have a new rubber host to the throttle house and the vris works perfect BUT
now I have strange behavier when i´m hiting the gas pedal the engine is very slow and sometimes i put the gaspedal all the way down and its not reacting much, only around 3000 rpm not more.

It sometimes dies when the rpm goes down to much. I have a little leak on the exhaust system in the back but that could not do so much problem like this??

???

Have you replaced all vacuum hoses by new ones?

Because especially when you changed the engine and reused old hoses they can leak....

No but they are fine.
Have used startgas all over the engine without any reaction.

This method is good to find leakages in intake system. But not in the vacuum control system.


How you are sure?
I recommend again, to replace all vaccum hoses. Just because of the age!

I also have a misfire around 1300rpm as most.
Could it be the ignition coil?

Check the ignition cables and plugs. If they are oiled the ignition can fail.

I will do that but its strange!

No faultycode.
If i do kickdown the car will rev good but after it loses the power
And in will only go upp to 2500-3000rpm and sound strange " blrrrrrrrrr" not wrauum.

Also it smeels like it desnt get the correct mixturr with air and petrol.
