M50b25 misfire after cleaning

[Benjer182]

So you know how it goes you show your new car some love in the shape of a good ol fashioned clean including the engine bay and then woomp there it is a misfire, now I know a bit about engines but this is my first bmw, I've taken the coils out and dried down the holes where the plugs live and checked the electrical plugs on the air flow meter and throttle body but it is still playing silly buggers, it was ok earlier when I started it on the drive but after driving a couple of minutes the misfire returned, I assumed when it first happened on Saturday that somewhere would be wet but it's still doing it, so where do I start looking on one of these ?

Thanks in advance

Fuse box? Ecu?

The fuse box didn't really get wet to be honest I was careful of that, where does the ecu live on a e30 ?

[Benjer182]

It's a 2.5 from a e36 and I've been told it's a non vanos one

Ok will do, I'll go out and have a look tomorrow evening

Or probably you bust one of the coils

Sorted now it was just dirt down on one of the spark plug tops
