I just finished swapping a new B230F into my 240 after the last one threw a rod out of both sides of the case. It drives well, but idles rough and consistently turns on the check engine light with codes...
1-1-3 ? Lambda control ? engine running too rich/lean
2-3-2 ? Lambda control ? too lean or too rich at idle
If i clear them they come back after about 10-20 minutes of driving. i'm looking for some help with debugging it.
The new engine is '93 B230F squirter block with a T cam, and my car is a +T (13c) with an intercooler. The old engine ran happily with the same setup and didn't throw any codes.
not sure its related but my boost gauge (volvo triple gauge with no numbers on it) reads less vacuum then i recall it used to at idle, the needle is level at idle and dips (more vacuum) when the engine revs up before climbing up into boost as the load increases. So...air leak on the intake side?
I think i did things right when i put things back together, used new gaskets and such.
What should i be checking to get to the root cause?
my next plan is get some ether and start spraying things on the intake side.
