id tank to tank it to check or the computer is fucked

 

korean tune up maybe

 

thats insane

 

99% of time panda is town and does 49 mpg

 

too many accy hills m9

[hairnet]

Would that not flag up code light? Hadnt thought to scan it. Will frag tomorrow to see if anybody gives me money for it

It didn't in the presidential Renner. Just poor mpg. Until MOT time when its hydrocarbons were 6 times the permissible limit. That was when the sensors came in for scrutiny. If the upstream one is not reading, the ecu assumes the worst and massively overfuels to avoid an overlean fuel air mix that would heat up the cylinder head too much. Of course the cat can suffer as a result, but in the Renner's case I got to it in time.

Its weird, sometimes with an Auto a 3.0ltr can give the same mpg as a 1.6.

Well that's one I tell myself when I'm in the S430

I think that's often because those big engined cars have a much better gearbox than the smaller engines. Better in that they have torque converter lockup in lower gears and they use it more often. Also more gears for efficiency.

 

I know the AW55 in my old Laguna and Saab 9-5 would lock up in 3rd, 4th and 5th. Also as the engines have more torque and power, so they don't have to change gear as often. Changing gear means lockup disengaging and so losses in the fluid during the shifting process. Being more advanced boxes and engines, they often do other clever stuff too. Like the AW55 deliberately slipping when changing to smoothen and quicken the changes.

 

Once a gearbox has gone into lockup, the engine drive is directly coupled through the gearing. Hence no hydraulic losses, that usually make them suffer.

The revs to speed difference between my old gooners 5 speed autobox and the new gooners 6 speed manual is pretty similar, which surprised me a bit.

Maybe the car is fine and she's just been sneaking away for track days when she says she's been at work.

Is best way to check sensors by reading them with OBD2 and see if they are switching?

 

I reset the trip computer so will get a real reading, but I don't think it is far off.

 

I would expect the mpg to be more like 26-27 ish. As said these aren't massive frugal. Focus and the civic both with 1.6 autos got about that .

 

Shame she doesn't want her old Saab back (too big) that was miles better.

[dollywobbler]

Check the running temp too. When the Nippa's temp sensor was duff, it was running over-rich as the ECU didn't think the engine was up to temp.

It gets warm (about a third on temp gauge). Hadn't thought about thermostat. Will see how easy that is to change.

[The Moog]

Decided to quickly change the thermostat last night before going out.

 

One of those jobs that should take 5 minutes right. Except it was being done by torchlight.

 

Airbox lid off.

 

 

Next a 15 minute battle to get the bottom bit out. There was a hidden bolt at the back which was a pig to get at.

 

Finally accessed the thermostat.

 

Access was shit so the battery was off next.

 

After that it was pretty straight forward.

 

Next up was plugs - were a little skanky

 

 

Air filter was a bit manky as well

 

Aside from driving the car after not topping up the coolant all seems well. Will see if it effects the mpgs

[The Moog]

So took the getz up to Scotland for the weekend.

 

On the way up doing 75mph the mpg said 26.4.

 

I had left a bottle of cataclean at Moog in laws house so lobbed that in. Return trip said 30.2 on way home which was an improvement.

 

I also did a brim to brim calc and used 39.5l for 300miles.

 

Doing sums that comes in at around 34 mpg - which is probably rightish for this.

 

Are these computers that far off?

 

Edit: I wonder if it is doing it in US? The temp is on farenheit for outside temp.

Sounds about right. 1.2 US gallons per Imperial gallon.

You didn't say that whilst going sideways round Knockhill in the starlet!

[The Moog]

Just seems a bit of an odd thing to do. I can't find instructions anywhere to convert outside temp into celsius either.

[hairnet]

wheelbase too short couldnt catch it

 

also weather conditions and cunts in seats

[The Moog]

Scanned the 02 sensors

 

I think this might be the problem.

 

I unplugged the sensor under the heat shield and that flatlined the first sensor. So definitely will be the one in the exhaust

 

Hunting for the parts is a bit of a pain as they seems to flag up the first precat sensor - not the exhaust one.

 

Edit: ignore that found some on ebay

[The Moog]

Just spent an enjoyable week mostly underwater in Egypt.

 

But on way to and from said managed drowning I got some spots*

 

I do heart the big pug estates they run out there.

 

* Maybe shit

[The Moog]

As the weather wasn't too bad I decided to have a go at the Puma gearbox mount. I ordered one from eBay (it was very cheap) before Christmas

 

 

The issue is that with a lower front strut brace it knocks. Normally caused by worn engine mounts. As it is coming from gearbox end I thought I would start there.

 

Firstly I had to fix my jack. The little bung has disappeared so just gaffer taped it for now.

 

In time honoured tradition it was off with battery and battery box to get at the offending article

 

Cam cover gasket still needs changing. I used a pattern part last time and it hasn't sealed well.

 

And now it is revealed

 

Then the fun began. It was a real nightmare to get off. The bolts holding it to the chassis were only accessible a little bit requiring a ratchet spanner and a million turns.

 

 

After about 20 mins the old mount was off. It is really floppy and I could easily twist it. I am sure it has seen better days

 

Just a case of reassembly is just putting stuff back isn't it..... Errrr no.

 

First challenge was the new mounts bolt holes were too small.

 

After some gentle hammer taps I decided to enlarge them with a drill. No expense spared workshop time

 

I stopped taking photos after this.

 

The mount then could be assembled but I couldn't get the bolts that go into the chassis in. After about an hour of swearing I had one in and one partially in. With grumpy missus Moog I called it a night.

 

Will go back and start afresh tomorrow.

 

Putting things away I noticed that part of the reason it isn't that simple is that the lower strut brace is holding the gearbox up. Therefore there isn't enough room to lower it to get easy access to the bolts.

 

Will have another look tomorrow but might have to take the brace off before reassembly of the mount.

[Bucketeer]

Some red hot driveway action there.

I think I'd have given up long before you and just bought something else to tide me over 'til I could be bothered to put it all back together.

[320touring]

That looks a cunt of a job - well done for not losing the rag!

 

Hope it goes back together ok tomorrow

[The Moog]

Round two

 

Decided that whipping the airbox out might help.

 

Managed to get the bolt out, cleaned and then back in. Rachet spanners are a god send.

 

Not 100% sure about the quality of the mount. The part that bolts to the gearbox mount means threads just reach top of nuts. I think they are meant to protrude bit more.

 

Did them up tight and all seems firm. Worst that can happen is that I have to replace the mount again, now I have the knack.

 

All back and in for a test drive.

 

Difference to knocking on strut brace... Zero.

 

So choices are 1) replace other two mounts 2) take some metal off the gearbox case 3) ignore it

 

Choosing 3 for now. Will be moving this on in the near future as I have already lined up a replacement.

 

Before then I need to do something about the rust rear arch.

[NorthernMonkey]

I still say number two is the one to go for. Not too much, though.

[The Moog]

I think if i was keeping it then that would be a plan. More likely to take it off and sell car without it so at least it doesn't sound awful.

[twosmoke300]

Can't you spacer the brace with washers or put a dent in it to clear ?

[The Moog]

The brace comes off the lower arm bolts so spacers I don't think would work.

 

A dent would

 

Not sure how it would effect its structural integrity

[The Moog]

Clear crisp day so what better than to tidy the garage... Ish

 

From a cluttered heap

 

To an organised heap.

 

I have got about 10 tool boxes to sort out yet.

[Bucketeer]

Have you put the dart board up yet?

[The Moog]

On the list to do ...
