Huge increase on fuel consumption.

I have gone from a regular 30mpg over many thousand miles to 23mpg!!!!

I changed my plenum over the other day for my polished one, could this have caused this.

Car does feel quicker though, maybe it was matched better?

plenum alone wont do that.

might want to check for air leaks and all sensors working properly.

I took my fuel rail guard off the other day and the same has happened, hope nothing has got damaged.

will check it all over tomorrow, should i get someone to rev car up and listen around the seals?

I usually forget something, but i didnt have any spare bolts left over this time.:clown:
