Helloo everyone... phew... finally i found some time to be active in the thread. been damn busy lately. there is some news about my car.some good and most not so good 
2 days ago... a dog decided to hit itself @ 80km/h into the right corner of my (newly painted) bumper
result was a dent n lot of chipped paint and also a crack in the bumper 
got it repaired yesterday. The workshop was over crowded so couldnt get the paint thingy done. the bump is poped out and crack repaired.will get it painted after eid.
Second thing. Got its front wheel bearings changed (1750rs/piece) got tappets and throttle body done.changed the fuel filter, got the injectors clean (they were in a bad state) , got a new battery, got wheel adjusted. total 8000rs was spend around 2 weeks ago. the main reason this job was done was to replace the bearing (this went fine) and fix the issues with fuel filter. apparently, the fuel filter n injectors were the culprit. engine wouldnt respond at times when driven on petrol (its perfect on cng)
After those 6hrs and 8000rs spent, the problem wasnt solved
i did improve though. but still, acceleration on petrol is around 20% less then that on CNG... i cant really think of anything other now. may be its some sensor. Workshops are closed down now so will get it checked after eid. i know all the injectors are working fine now.fuel filter is new, may be there is sumthing wrong with the fuel lines.
will be posting pix in a few mins...
