Hi all!
First post on the forum, after some help and advice. Bought a lupo 1.0 MPI as a cheap runaround for the next year of university, parking space in my apartment block is tiny so lupo it is! On the drive home it started hesitating and losing power on the motorway section, which luckily wasn't too long so I made it home fine but it's definitely misfiring and my scan tool confirmed it's cylinder 4 along with lean fuel trim.
I've done some reading on the forums, seems spark plugs, leads and coil packs are a must and they looked quite old so I've bought new ones which are in the post. While they're on their way I decided to clean the throttle body which cleaned up lovely, but I also wanted to clean the egr but couldn't find it?? Very confused because maybe the engine doesn't have one but most posts suggest cleaning it so maybe I'm being brain-dead but does the ALD engine have an egr?
If the plugs and leads do nothing I will put a new fuel filter in anyways and check for fuel pressure, fingers crossed the plugs and leads fix it, coil pack after. I'll do a compression test too and get back with the results when the tool arrives, I know about the +-10% rule but any PSI values I should be aiming for?
Would appreciate any advice or help from you guys, hopefully get the car running sweet before uni, I'm not afraid of doing a head gasket or anything either but let's try the easy stuff first haha
Cheers!
