Use a spray disinfectant/deoderiser specific for a/c units,as all a/c harbour legionaires bugs,it will kill them and all other nasties in the system...also make sure the airbox inlet is free of leaves etc...

Jeep grand cherokee 2.7crd.only has done 120000miles

The number 1 root cause for poor fuel economy is a vehicle running to rich, whether it be through a fouled spark plug, faulty ingintion coil, O2 sensor not functioning properly, and even through dirty injectors. I'd start by first inspecting your plugs and replacing them if its been a significant while since they've been changed. Standard heat index plugs normally last around 50k miles, newer specialty plugs like irridium electrodes generally last twice that. Sometimes you can easily check for bad ignition coils by first smelling them. If the winding is bad you'll have a strong burnt electrical odor, you can also visually inspect for any oil around boot from a bad gasket. That could potentially short one out. I would smell the exhaust to see if it is running rich (strong gas odor) that is an indication that one of my suggestions are at fault. If you have a d.o.t emissions testing facility nearby they can measure exhaust vapors for excessive hydrocarbon output too as well as for any trouble codes that may be in your system (Tn does for a $10 fee) I would also try adding a bottle of isoheet and a good fuel injector cleaner additive at least evrery 3rd or 4th fill up. Let me know what how these suggestions work for you and if you have any further questions

How do I change the spark plugs on a 2007 5.7 hemi engine?

2 plugs per cylinder "I guess that makes it exotic"

You will need 16 plugs. And they come OEM with copper. Plat plugs do not give you better performance. They just last a little bit longer and cost more money.

take the 4 torc screws out of each coil pack.

Unplug the coil pack.

Pull the coil pack straight out. Turn it over and check for cracks. "For all 8 it will cost you 400-600 dollars"

Plugs are down in the holes your coil pack tubes just came out of.

Change them the same way u would pull any other plug.

Check the plugs for fouling or oil. You may have to change your gaskets. They sell a valve cover gasket set with plug tube gaskets for 30-50 dollars.
