I have a big problem with one of my cars.....
At cold condition it runs so good, no misfiring etc... but when it begin to get warm the engine starts to loose its breath like your'e strangle it, and begins to misfire. At some moments the power comes back and runs like normal. But the idling is really smooth. The ignition parts is just changed (plugs, leads, and the distributor) with no success, it's also the right timing.
When I rich the mixture it gets rougher idling but it runs like a beast and no misfiring at all, but smokes black
The hoses and diaphragm (right word?) is unbroken, checked with "motor starter"
OVP, Fuel pump relay and KE-box have been Resoldered on suspiciuous cold-soldering spots with no change
Going to test the piece-of-**** with the Oxyen sensor unplugged to see what that gives, the cat is empty, as well the small "pre-cats"/"spark-eaters"
And the fuel consumption.... 20 litres per 100 kilometres
