had thos problem since put m50 in , lumpy idle but unplug maf and runs fine , and runs rich too , not 100% sure its the maf , could it be the m20 temp sensor or air temp sensor and just to check im being paranoid but with the icv the arrow points towards the manifold not the intake boot ??? how do i check these with no diagnostics ?

m20 brown temp is just for the clocks and not to the ECU, arrow is to the manifold. could be o2 sensor, mine said MAF cleared the faults. cleared it again and just o2 bank2. pay the money any good garage wouldnt charge you if no faults come up
