hello,
i have restored the engine of my bmw e21 323i
the new spark plugs work fine (ignition ok)
it has cis (k-jet) injection
a gaskets on the engine, intake and exhaust are new ones, so is the are filter
the fuel distribution works fine when i lift the air sensor manually ( injectors are spraying gasoline)
but when i try to start it, i only get my injectors spray when i press full throtlle, followed by a bang and yellow smoke in the intake
when i crank the engine without full throtlle, i get no injector spray
what is the problem here? maybe a vacuum or air problem?
can you help me?
many thanks
geert
