Check Engine F%$*n Light Illuminated

[MOUTH]

So I cleaned my cruise control radar on the weekend and now my cruise works perfectly again. Let my car idle for 5 minutes after a big drive when i got home, . Go to turn it off and the check engine light is on, I thought it would just be the brake pedal sensor, took for a spin with the brake pedal switch "off" and it still didn't clear. So this morning I checked the codes and I get 0235 and 0171

0235 Turbocharger Boost Sensor A Circuit Malfunction

0171 System too Lean (Bank 1)

Anyway I am pretty Stoked , thinking maybe boost solenoid is caput? anyone else ever had a fauly like this? Please help if you can

Also at idle I get a very little miss I can hear and just see on the tacho, so going to do plugs etc aswell...............

Mmm, fuel regulator reference hose will definitely make it run lean. I eventually put cable ties around mine to stop this happening. Why did this make the boost sensor come up though?

yeah I just ziptied them too, dont have a clue about the boost sensor though, I am just running evrything stock (no boost controller etc)

Maybe because a decent amount of boost would bleed out of that pipe....?

No, not much, its only a 2.5mm hole. Perhaps it throws a code if theres not enough vac but I doubt it.

Just another M35 mystery then .
