I am facing some issues with my car:
Honda Civic vti oriel prosmatic 2005
Petrol 68k totally stock.
Car is driven with very light foot.
A/C is not being used till nw.
Firstly,its giving max 280-300km in full tank petrol(also tried mixing hi octane). I got it tuned... plugs were cleaned and installed,new air filter,oil change,throttle body opened and cleaned...but still no effect on consumption. After getting throttle body cleaned RPM started bouncing between 1k-2k rpm while driving, again went to mechanic and got it fixed but now rpm comes down to 0.8 idle rpm and then bounce back to 1.5k and now what mechanic said is that drive it for 2-3 days it gona get fixed automatically as its happen sometimes after cleaning throttle body and mileage is still the same.
Secondly i got all four discs tooled as they were producing lil vibration while braking(But breaking was awesome).Now there is no vibration but ABS get engaged even in slow speed and car doesnt even stop. Got it checked 2 times, brake pads are new, got them cleaned 2 times but still same issue.Tires are in good condition.
So guys need help in improving mileage (atleast it should give 9-10km/litre,correct me if i am wrong) including the RPM problem. Secondly where to get the brakes fixed? Any good reliable mechanic in isb/rwp to fix these issues. Thanks in advance.
