Having a few very small issues but it's causing me to worry so hoping to get it sorted so I can go back to enjoying my car rather than worrying about eveyr single thing...
#1 - Very, very minor misfire at idle when warm. Like rev counter doesnt move, engine doesn't cut out but every second say there's a hiccough and the engine faulters, can feel it when sitting inside and hear the tiny 'thump' through the exhaust. Very very very minor, like I doubt anyone else would notice it. Car's running fine, plenty of power and no noticeable difference. AS far as I can tell the msifire became apparent after replacing the spark plugs - Used BKR6EIX-11 NGK plugs which are pre-gapped
#2 - Petrol smell, I don't know if this is because I have a decat but there's a pretty rich petrol smell coming from the exhaust when I start the car or come to a stop and the fumes drift into the cabin (rarely) but when I get out I can smell petrol in the air. I've checked the safety warning thread and the metal brake/fuel lines under the rear sub are fine and no leaks or bad stuff. Charcoal filter is still fitted too.
#3 - Getting about 18mpg for gentle a-road and maybe 20% town/suburban driving. Seems other people are getting 20-22mpg for normal driving even in towns. The o2 sensor has been replaced for a new denso one, brakes aren't seized (can't hear the pads dragging on disks at low speed, but when i coast the car stops quickly below 5mph but think that's the fat tyres/weight pressing down on them).
Known issues that may be of interest/going to eliminate these and see where I am regarding the above niggles.
- Coolant/heater hoses at the back of the engine weep when the heating's on slightly so drains the coolant a bit.
- Front tyres are due replacing & probably need alignment
- Fuel filter needs replacing (tonight) and fuel filter (K&N) needs cleaning and oiling
Also what's the turbo vvti cambelt change interval times? 60months/90k miles? I think it was done two years ago at about 80k miles but not sure, one resource said it needs doing yearly or every 12,000 miles after the initial replacement
