Help, no EML, problems...
« on: 22 February 2007, 14:05:56 »
Well I have just got the parts in to do all the work on my 3.0 1995 Elite (Cambelt kit + forum DVD, water pump, rocker gaskets etc) this weekend and now just my luck! this bloody thing has developed a fault :(

Once its warmed up a bit its running lumpy/misfiring like its running on 3 cylinders.
Last weekend I cleaned the breathers, checked the plugs/leads - it all looks ok, nothing swimming in oil.

I was going to check the EML, except there is no EML even when just the ignition is turned on? this does not seem right? has the previous owner taken the bulb out??  :(

Any advice on what to check/ possible common causes on this engine?

EML should come on  for a few seconds when starting.  If you get a working bulb in there you can read the fault codes with a paperclip.  i'll dig about for a more detailed description of how to do it

Pop the instrument panel out (see the maintenance guide section, its dead easy) and fit a bulb....then check for codes...

Hmm, does sound like some idiot has removed the bulb, though I guess its possible it has blown (uncommon)

Well I have taken the panel out and found someone had removed the bulb and holder!!!  :-[ very pissed off!

Fired it up and the EML is on.

Paperclip test shows 69, 144, 145 and 135?

IIRC, 144/145 are immobiliser, probably old and can be ignored for now. 135 is no bulb in dash (now repaired, so 69, not one I've heard off so will check TIS.

Intake air temperature is greater than 140 °C (284 °F)
(Short circuit to ground)
Replacement Value:

The control unit takes 20 °C (68 °F) as replacement value.
Effect:

The learn functions (oxygen sensor control, idle air control and knock control) are locked and the last valid values are used for calculation.

Has the inlet trunking been removed recently.....is the multiram plug incorrectly fitted into the temp sensor and vice versa?

Well I have just been out and checked.
Whoever had been there before had cable-tied the connectors in place and connected the wrong away around (multiram plug incorrectly fitted into the temp sensor) as Mark said!!

This must of been why they took the bulb out as the EML has now cleared.

Once the engine was warmed up, the misfiring comes back though...

Any new codes?  If not, I would suspect HT stuff...

I have it all sorted now.

I have spent all of yesterday until 1am working on this car and uncovered a multitude of sins.
Replaced the cambelt and waterpump with help from the DVD – easy job really!
There was a chuck missing from the belt so I got to it just in time. It was also poorly fitted – cams 1&2 where a tooth out more or less.
There were no bolts fitted to the cambelt backing plate so this was rubbing on the tensioners. The waterpump pully had only 1 bolt holding it on.
I replaced the camcover seals, someone had sealed them up with a cement type sealant so it took me two hours to carefully clean up the covers and apply the new gaskets, o-rings and correct black sealant.
Replaced plugs and HT leads and flushed the cooling system.

Much more responsive and smoother and the problem has gone.  :)
