Technical Strange Knocking, poor idle, fuel mixture

timmyyo198 · Jun 9, 2015

So The engine management light came on not so long ago, straight after I decat my exhaust, it all seemed to run well, the eml went off after i'd been for a long drive, now it's on. I started my car this morning and it's messed up, the engine is knocking really badly, smell of fuel, it's hard to start the car aswell, idle is all over the place,

Please help!

Well the decat is probably messing up the fuel mixture
As it trys to correct what it see's

Due the pre /post lambdas

Get a code read to see what the ecu is thinking

Just checked my oil, there was not even a drop left

, I think the engines gone, misfiring like crazy, engine knocking constantly, idle is all over the place

When dipstick is not showing, the oil pickup is JUST covered IIRC
Soon as it cant suck up - the oil light SHOULD come on
Just like when you first put the ignition on - the lights on till it starts and should be out very very quickly afterwards (unless its a rebuild)
