Hi,

i recently got my first E30. Its a 325 in good condition with around 190kkm on clock. The car goes well, has a clean engine, it doesnt burn much oil (so far around 1 litre / 10kkm estimated :)) etc.

A few days ago it started to act funny tho. It works fine when cold and after its warmed up. But if i turn it off warm, wait for 10, 20 minutes and start it again it doesnt run on all 6 cilinders, it responds on gas pedal very bad and sometimes it dies and it doesnt have any power so i cant even drive. There is a strong smell of unburnt fuel.

If i floor it if somehow wakes up, and after a few more agressive kilometers its all back to normal.

Well almost, now i started to listen to engine when driving normaly and there is a slight misfire now and then and i noticed a few really mild "bangs" from exhaust and some smell of unburnt fuel.

Anyone has an idea what could be wrong or what should i check first.

I took out spark plugs and they look dry, light gray in color. They are only a few months old and the car drove only 1500km with them.

I'm not 100% sure but just a thought - a leaky injector could cause it to run rich and partially flood the engine, giving the fuel smell, difficult starting when hot and bangs as the unburnt fuel is ignited in the exhaust pipe.
Could be something else mind! I'll have a think!
