noctalunais

So! I have a 180sx currently running a s13 red top sr20det engine imported from Japan, and it's been giving me some strange issues for a while now.

For some reason it seems to be over fueling and hesitating/ lagging at high revs when it's warm. To the point where it feels like it's barely making boost but it goes fine when cold. Which really confuses me! It seems to run better and faster when it's cold.

I've checked and cleaned the afm, added a splitfire coil pack, checked for boost leaks, just about everything I can think of. I'd love to run the ecu codes but unfortunately the plastic screw thing you need to turn has been threaded really badly so I can't do it at all.

I'm trying to get to the knock sensor at the moment but the bastard is just in the most innacessable place; even then I'm not sure if it's connected in the first place.

It starts fine every time, idles perfectly, doesn't blow any smoke and aside from this issue runs like a dream.

I would really appreciate any help to finally get this issue sorted!
