hi guys

i have noticed of late that my mpg on the trip computer has fell through the floor last night i could only manage 35 mpg this was a mix of driving

it all started after putting my amp power cable in and i am worried that i could have broken something is this behaviour normal

i also have only done 150 miles to half a tank

the car is an 06 plate with 5300 miles on the clock

cheers guys

cold weather knocks the mpg down , see the other thread about this , also the newer EURO4 cars seem to have worse fuel consumption than the older EURO3 cars

but even when the weather is mild it is rare it will reach 40 mpg before i hooked up the amp power cable i was getting 45 mpg +

Unplug it and see if it improves

thinking about it i attatched the cable between the battery terminal and the engine power cable well thats what i think it is it attaches to the left hand side of the positive terminal if i move the cable and stick it elsewhere would this possibly cure the problem
