Hi guys,

I noticed today that where the passengers feet go, it is leaking water(or something).

Im assuming that the big white box under there is the air con?

I had a look under their and its coming from the white box (air con? again not sure).

Can anyone help me resolve this problem?

Thanks

Stel

Yes it's the aircon unit (evaporator) and the water is probably due to a blocked drain hose. Condensation from the evaporator drops to the bottom of the box and drained to the outside of the car through a rubber hose that passes through the firewall into the engine bay. The hose will be attached somewhere near the bottom of the box. You need to check it isn't blocked in the engine bay (look for a black hose coming fom the firewall on the passenger probably with a right angle bend toward the road), or by crap that gathers in the bottom of the box after many years of use.

Thanks for the info mate.

I will have a look tomorrow.

There is another possibility....heater core. In that case tho the leaking fluid will be either green if your using coolant (although some coolants are red) or rust coloured water if your not (and that would probably explain the leak). Let's hope it's not the heater core.

yeah could well be heater core so check for loss of coolant....and if it is get ready for a big labour bill from the mechanic or a frustrating weeekend if you do it yourself.

All for a couple of cm of rubber pipe.....

oh man. heater core replacement is generally about 10 hours labour if you are using a good, quick mechanic. if they are slow, it will be more.

when the heater core exploded on our daihatsu we just looped the hoses and bypassed it. not recomended though as the heater can be useful for demisting the screen. either way you need to get it seen to asap.

My heater core went a little while ago... haven't gotten around to replacing it yet - just looped the coolant lines until I can be f**ked ripping the dash out...

yep...

by passed it today...

I just couldn't be bothered mucking around with taking the dash out.

I got quoted from 2 mechanic's, one 700 (performance mechanic) and another mechanic (who im selling his business for him) 1300.

FU*K THAT! lol

I think i would rather freeze in winter....

Thanks for the help guys :blink:

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.

      If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
