B18c2 sounding like a rotary

[iceey]

I just recently purchased a 1994 integra vtir it was fine at first but when the aircon was turned on proceeded to sound like a rotary, and was flashing CEL 14 (IACV) .. I ordered another IACV from honbits was running fine for 30mins and came back.


Any help or suggestions would be great ..

Try changing your spark plugs

[trism]

plugs, leads, oil, o2 sensor, could be heaps of things.

You mean sound like a rotary as in lumpy idle?

Ill try the plugs tomorrow ..

And I've already adjusted the Fast idle control valve with no success .. Plus is throwing CEL 14

so i bought a new IACV.. i cleaned it installed it and it ran heaps fine for 2 days then when giving a proper go entering m2 the light CEL came back again with the same code

when i got to work i removed it and it was filthy as.. so i cleaned it again and its running fine again ..

anyone know why it get so dirty so quickly ?

Flush your coolant
and clean your air filter

give it another clean and you'll be fine.
Coolant leak will also cause a lumpy idle if not bleeded

so a coolant leak can cause this aswel?

i think i do have a coolant leak.. ill try seal that up

It can but unless its drematic it shouldn't cause a rotary noise. u sure ur mates not playing with u and swapping the map sensor and tps sensor around? haha.
Just make sure ur coolant isn't dirty, give it a flush, bleed it and clean ur air filter.
should be fine after that unless u brought a faulty iacv which does happen quite often.

u said u played with ur idle screw, adjust it back so it doesn't cause a problem. goodluck!

Ahaha nah I'm pretty sure they aren't playing with me ahaha

Umm yeah I'm on my 3rd IACV so far .. And it can't always be faulty .. I think it's just getting dirty real fast, can anything cause that ?

Yeah I'll do the coolant flush soon and ill make sure to change the air filter ..

And I'll get back to you guys thanx

If your new IACV is covered in oil then check and change the PCV valve.
It seems that the PCV valve is allowing oil to flow back into your intake and collecting on your IACV.

i flushed out the cooling system helped for a bit but started again on the way to work ..

the day i flushed it out i cleaned the sensor..

could the air temp sensor have anything to do with it ? coz i took it out today and it was oily as furk ..
