Hi, Sounds like you removed the battery to re-charge this then needs to have the computer system re-set before anything will work back to normal. Hopefully your nearest dealer may be able to send a mechanic out to try & re-set the computer. Should you ever have battery problem next time re-charge whilst battery is still in car with the connectors still attached. Please leave me feedback, Malcolm Campbell.

You will find the filter under the car in front of rear wheels.
It will have a cover on it so remove the screws to get to the filter.If you need to change it read the manual or you can get fuel all over the floor. As well as the filter you will need the copper washers that go in to seal the banjo joints.

Does it have a throttle cable? if not the idle is controlled by an computer controlled electronic throttle control stepper motor

installing radios into electronic controlled cars can be a real nightmare as the wrong wires used creates many CPU problems . Best have it installed by professional radio fitters at the shop where you bought the wireless and save your self a headache.

I would start by replacing your automatic air intake and throtle body sensor. Check these 2 things out and let me know.

Big breather from valve cover to air cleaner, the small vac line runs from there to the FPR.

These next are standing in front of the car:

Intake manifold lower outer runs to EZL

Intake manifold lower inner (right side) goes to switchover vac valve on driver fender. The other side of this vac valve goes to the throttle body

Intake manifold lower inner (left side) goes to switchover vac valves on passenger side fender. These then go back to the EGR valve once making a loop under the distributor cap for whatever reason.

Intake manifold rear runs to a 'three' way valve (or 'Y' connector) on the secondary firewall. This is usually a vac leak.

Under the dash . Remove the glove box to see it. It is the sampling fan that blows cabin air past a temperature sensor to allow the automatic heating system HVAC to keep temperature you set, steady.

The HVAC will work just fine without it although you may have to fine tune the temperature setting from time to time.

Most often this is due to a loose armrest mounting bolt or worn limit washer, unzip the cover and tighten the arm rest first, it is most likely a T45 Torx female bolt head AKA star drive.
