My brother had started to look for a new car as he's getting annoyed with his Civic because he says it's not performing as well as it used to and the economy is also about 10mpg less than it was two to three years ago. I've managed to convince him to keep it until I've had a good look at things but any thoughts what could be causing the performance drop and also the reduction with economy? It's the same commute that he's always done. I serviced it in December with good oil, oil filter, air filter and cabin filter. The fuel filter was done at a garage not long before that so I never did it. I'm thinking is there an EGR valve that can be cleaned like the Mondeo? Also what about the inlet manifold, is it worth taking it off to see if it needs cleaned? I've got some of that good injector cleaner at work which I'm going to put in the system. Also, his VSA and ABS light comes on. His pads are fine, could this be a loose wire somewhere causing it? If he ends up changing his car then he's wanting something not so harsh, his is the Sport and you really feel the bumps, has a bit of poke but is also economical. Oh, and a petrol and the same price as his current car. He's been looking at SAABs, Seat Leon's and the Exeo. I did point out though that he could get a 1.8 petrol Civic EX which should be better on the bumps, comes fully loaded and is actually very economical considering it's still got decent enough performance.
