First thoughts would be to scan the ECU and see what codes are stored.
Otherwise, if it is temperature related when the fault occurs then it may be the Coolant Temperature Sensor at fault
Is the coil pack a combined one (e.g. 4 coils on a rail) or are they individual coils?
Also, have a look at the wiring going to number 3 cylinder coil pack for damage
Hi
SOunds like an electrical connection has some corrosion in it
Worth removing the plastic panel underneath the windscreen to access the wiper motor to then remove the connector block and see what the condition is like.
Hi....welcome to the Forum
Without seeing which type of pulley attached to it I couldn't say if there is any slots in there that you can put a bar through to lock the assembly to tighten the nut.
As it is on a taper by the look of it it won't take much to tighten down.
Let us know how you get on with it
Hi Neil....welcome to the Forum
It sounds like the turbo vanes are gummed up with carbon which is a common fault.
If the car drives fine until a load is applied (turbo boosting) then the vanes which are supposed to throw out to vary the pitch to improve the delivery of boost tend to stick and cause the engine to go into limp home mode.
There are kits you can buy and lots of info on you-tube/google about how to clean the vanes and then once cleaned you just need to drive it hard to keep them clear of carbon deposits.

Absolute bargain Andy!
I always believe that there cannot be too much wrong with a vehicle if it achieved a huge mileage count, it would only have got there if it was reliable and maintained correctly over its life.
For that money I would just keep driving it until it expires but keeping on top of all maintenance to ensure it carries on for many years.
Post up some pics of the two if you want, it would be interesting to see the comparison of the two cars
Hi...welcome to the forums
I always wanted a Magnum but also a Firenza, out of my financial reach, even back then.
quite a selection of interesting vehicles there....lots of British ones in there
Good to have you onboard
Cheers, Trevor
Hi.....welcome to the Forum
I have no personal knowledge of the bluetooth setup using an adapter, but I think it will need coding into the vehicle for the functions to work on the wheel.
Hopefully someone on here has done this before and gets back to you soon
Easiest method would be to take the plugs out and see how they look, e.g. wet with fuel
The gaps and tightening torque is critical to avoid premature coil failure
Sorry to hear about the mirror....bloody inconvenient
You could try something like Wynns or STP which may make a difference...I have used it in the dim and distant past when oil was not as good quality as it is nowadays and just needed an additive to enhance it and stop the lifters from tapping away.
Hi....welcome to the Forum
I would first start with removing the auxiliary drivebelts and run the engine for a very short period to see if the noise disappears.
Sometimes a crankshaft pulley that is breaking up can give this sort of noise and is a very simple and cheap fix.
If not, then refit them and nothing lost....then time to move onto the bottom end.
