Overheating Tuscan engine

[JamesSim]

Hi Folks,
My standard 4.0l engine is overheating and running really lumpy, both connections on the air box had snapped off.
It's just been serviced and when cold it's fine and smooth but as soon as the engine warms up and your sitting in traffic etc the heat is unbearable from the passenger side of the engine.
The air box connections were modified in the service but when I removed the engine cover, the front pipe had disconnected again, I haven't removed the air box cover to check the other yet.
Could this be the only reason or could it be HT leads etc?

Many thanks

James

Hi Matt,
I think it might be the cats, my son has ordered the 3 pin adaptor and has the software to investigate a little further,
My car hasn't been off Jersey for 8 years now and cats just do t get to operating speeds over here.
My dash readout isn't operating properly as it freezes if you try and interrogate it, it will display alarms such as low battery, oil pressure etc on startup.

Kind regards

James

Hi Andy,
Yes it was running rough before the service, and the heat is all around the cats and manifold, so much so that the paint is showing fine cracks above it on the bonnet.

Thanks once again Andy,
De-cat is the route I will be going down, in Jersey there is no legal requirement for Cats, they don't work here due to the too low speeds, modern cars are having to be continually reset as they often go into limp home mode.
I spoke with my service guys this morning, they were originally factory trained and have the diagnostic equipment, they have also said to bring it back in as they will give it a thorough examination and test drive.
My dash pod is a salvage replacement since the original went pop, however the original will be sent back for an overhaul, even though the original only had water temp, oil temp and pressure readouts due to it being a very early car.

Kind regards,

James
