Hello ya'll, kinda new to the DSM world but I learned so much lurking these couple months. I recently bought a 1G Mitsu eclipse, 100.000km (62.000 miles) in good shape, practically stock, GS (European trim, 150hp), LPG conversion kit installed and working.
Everything is fine, the only issue I'm encountering is kinda annoying: on cold startup, the engine doesn't spool high enough and after a brief power-on peak at 1500 RPM, it just drop and dies. I can try how many times I want but it still won't power on well and stabilise. I have to disengage the clutch and accelerate while remaining stationary or directly driving for 15s or so, after that it idles at 750 RPM, so the correct amount by reading online. It's really annoying if I have to get out of a tight parking stop. Once I'm driving, I have almost zero issues with rough idling. Engine may dies if I'm using the AC and coming to a stop. I know about having to adjust the BISS screw, but the stable 750 RPM once warmed up seems to indicate it is set correctly.
There doesn't seems to be any vacuum leaks, it's an aspirated engine so not much stress on the hoses. I've heard it might be an issue with the o2 sensor needing to warmup before sending the correct amount of air, but I've read conflicting information. Engine seems to be running correctly (no visible black fumes coming out, although it might be running lean...).
I'll be going to a mechanic soon but he has no experience in DSM (kinda rare nowadays where I live), so I wanted to narrow down the culprit, maybe if any of you is in the same boat and solved this issue.
Sorry if it seems stupid, but most posts online are talking about too HIGH rpm on idle, instead of too low.
Any help is kindly appreciated
