The bulb for EML is fine as it shows when the ignition is turned on, then goes off.

I'm taking my issues as 2 separate ones tbh. An idle problem and boost problem. The idle seems much better when the vacuum line for the dump valve is removed but not plugged. Plug it in and idle drops to 700ish rpm and car struggles. I have a replacement clean ICV to fit and will clean tps too and see what happens.
As far as the boost issue goes- I believe it is hitting the fuel cut and am wondering if the vac line between the compressor and actuator may be split somewhere, or maybe a problem with the actuator itself. My car runs a Lektron valve from escos, which itself is not working (no click when ignition comes on-need to test wiring and find replacement to test) and damaged. Input hose from compressor actuator is plugged for now til sorted.

Any advice or tips on anything like how-to for cleaning tps, removing ICV, checking actuator, Lektron, hosing etc from anyone?


Cheers
