Engine Management Light

Engine Management Light I believe is what we call Check Engine Light here in the US.

What fault codes are you getting?

It is also possible that you have a dirty or faulty MAF sensor.

Try cleaning your MAF sensor with MAF Spray Cleaner.

Without codes it is vv hard to asseas - it could be as simple as fuel cap not tight - who did the lamdas for you ?

 

Not possible to trigger a MIL/CEL without a code being stored unless the MIL/CEL circuit is is faulty - very unlikely. If it reoccurs try a £30 OBDII reader from ebay to read the code. A 360 does have OBDII I think??

 

As above no codes or faults is BS. For the computer to pop a CEL.. you WILL get a code. OBD reader (CAN) will read it for you. Then you will know what the computer thinks is wrong. Until you have that number it could be any number of things..

 

This will read F codes:

No idea on the vendor.

 

As others have stated the CEL (Check Engine Light) illuminates when one of the fault codes has been triggered from various sensors on the car. There are situations however when the CEL light is illuminated but an error code is not stored. One example is if the "SLOW DOWN" message comes on the dash due to faulty Cat control station.

Its pretty common for this to be from items like O2 Sensors (lambda) but they would have logged a fault code.

Q. Did the dealer tell you a O2 Fault code was raised or did they just 'guess' at your expense? I hope not!

Like others have said get an OBD-II scanner and look up the fault yourself or get the dealers to plug in their SD2 computer and tell you what fault is logged.

Here's a tip : most questions have been asked before

And that is why at the top of this section is a useful technical threads sticky - if your answer is not there try the 'search' function - 'scanner' or 'obd' should yield many many threads with suggestions - you can also try advanced search on the 360 section and/or titles only too to get better answers

The plug is under the dash more or less in line with the steering column

With this condition, you would be getting misfire codes when you read the OBD II / CAN report. This happened to me, it was localized to cylinders 2 and 5, though "random" misfire codes were also stored.

I had all of the intake manifold gaskets replaced - they were all original and in some state of decay. The worst ones were on #2 and #5. It was a big job because the top of the engine has to come off. Parts weren't that expensive - it was a big labor expense.

 

If MAF doesn't solve it you can try squirting some carb cleaner at the base of the intake stacks where they meet the engine with the engine running (cover face/wear protective eyewear as always). A drop in idle/running suggests bad gasket.

 

I had to replace these gaskets before after one leaked a few years ago. It didn't generate any CEL.

In terms of job size. It didn't actually take that long to whip off the red top intakes (surprised at how heavy they are though.. hmm may get a mould done in CF .... hmmm). The job is not as bad as you'd expect, about 2 hours removal, 2 installation. all in for me to remove and refit everything about 4 hours. The gaskets are just a few dollars each. I would also say this job is easily in the relm's of DIY. If you can do an oil service you can fix these gaskets. Its really not that hard..

When I did them I found that an extension shaft, electric driver and flex adaptor helped so well. Getting to some of the inner 10mm nuts is a pain. And as above, lifting it out is fun! putting it back in was also fun with reaching over everything! FYI don't overtorque the adapters to the 4 black vacuum lines in front and rear. they will crack! managed to get it out without undoing all the prior work. Also watch for material in the cylinder bored and check with a bores scope before reassembling for fallen washers etc!

 

Replace transmission cooler while in there??? I had mine replaced as a precautionary measure and they replaced the gaskets at the same time.

Can you try a new fuel cap ?

 

I also have the P1125 for 4 years I changed all the intake seals, air filter, canister, coils, MAF, PMB sensor, 4 lambda sensors, spark plugs, and despite all that still the fault, do you have a idea knowing that the exhaust manifolds had been dismantled and reassembled with the same gaskets!
