So, i was on a road trip 2 days ago. left from home at around 3pm on saturday. reached rawalpindi around 6.00pm. in the way when i switched to petrol on motorway kallar kahar area, the mountains were echoing of the knocking sound from my engine So i got high octane filled in as soon as i reached isb. and the knocking went away hardly after 4-6kms!!!
The same day, CNG was opened.got cng filled it. 707rs... 9+ kg. parked over night. left for gujranwala next day at 12.45pm and got gas refilled after a total of 25-30kms. got 166rs gas and decided not to get any more refills until cng is completely consumed. rwp to gujranwala from GT road is around 220kms. ups n downs on the road, gear shifts from 3-4-5 at times. we were 4 passengers with trunk half filled with luggage. as i got cng filled around 20kms out of rwp, we reached gujranwala on without needed any refill. at that time i saw 198kms on trip A. ( i always reset Trip A for gas refill and Trip B for the complete trip mileage i.e. home-destination-home)
anyways, left from gujrwanwala at 6.30pm, same day, same gas. and finally, finally, gas finished at 211.8kms!!! now that is SUPERB mileage!! drove 7kms on petrol and then got cng refilled. this was only the 4rd time that the 200km barrier was crossed
here are the mileage shots (@ filling station, 7kms later) and the load on the car (note how the tire is inside wheel well due to load)

Few things might have contributed to this mileage.
First off, people say "pindi ki gas bohot alla hy" i dont know what that means but may be theres SOMETHING. secondly, there is a gentle slope towards lahore from rawalpindi on GT road. though u also have to climb at a few places but its over all downhill and thirdly, the avg speed was between 100-110km/h. had it been 80-90km/h, i think it cud ve done 250kms guess how much fuel we waste on motorway doing 120km/h on small engines

other then mileage, i just LOVED the drive due to brand new chimta bushes. very stable and predictable. i dont remember any car over taking me, did 130km/h for a long time. Really enjoyed the picturesque view and nice drive

i don't know why he said that... :s he said the check engine light will how up and you will have to get it checked.. it happens when you open the throttle body and all... he also said that if it shows up he will try to turn it off by resetting the system.. but i am not comfortable about it because the other mechanic i went to he did the cars tuning last time and the yellow light did not show up... but he didn't do the throttle body and tappets..
also after doing that will the mileage of the car increase?

if done properly, yes, mileage SHOULD increase (i.e. if the car needs tuning, obviously if everything is alright even now, all of this wont enhance the mileage) and the check light shud not show up. better ask some of ur buddies or relatives or anyone for another, reliable and well reputed mechanic if u're not sure about this one. plus, u dont really need injector cleaning if ur car runs fine on petrol. this is not even a TUNING thing. only tappets and throttle body are needed in tuning. get that done...

thanks ahmad bhai.. right now what i am doing is that i will see the mileage because i have changed the air filter, the previous one was choked.. lets see how much difference in mileage i get.. once found out i will share it here and you guys will tell me about it.. if not good then we will go for other things such as the tappets, throttle body, fuel filter and etc etc.

Latest status as on 5th March 2012.... Fuel tank is now getting towards empty.... so i guess we will come to know the exact situation in a couple of days......

@fahad_reloaded
man... that is an exceptionally well done DIY. Mashallah performed very very professionally and the result speaks for itself... i can only wish i gather enough guts to do that all on my own shud be atleast 2 or 3 ppl doing this job. btw, how did u clean the floor? water? air? if water, how did u drain it? any problems fitting back anything? specially the seats?

Well @ahmed thanks for the compliments, being an engineer by education and profession, i am always inclined to do this kind to stuff myself. My level of curosity is very high for the tasks which i see other ppl doing, so the positive engery pushes me that if some other person can do it, why cant i do that. But, wait a minute, this doesnt mean that u mess with ur stuff , u shud be well versed with the procedure u r going to adopt and it is better that u shud first write the whole procedure for the tasks u r doing and review it so that it can be done seamlessly....

1. Interior is washed with water.
2. Then park the car on the ramp with front being upwards, in this way all the water is accumulated in the space for the spare tyre in the hood.
3. After all the water is accumulated use a simple pipe (used for watering) and suck out all the water easily
4. Allow the remaining water drops to dry naturally or get the cloth soak th remaining drops pratice will make u perfect
5. For the seat fittings, yeah i faced the problems but i fixed them out AlhamduLillah.

Its the trunk my friend....

i have done a lot of research on the "Check enginer light issue" for I-DSI model showing only on CNG and i want to share my findings with all of you.
If the check engine light is only showing on the CNG and not on Petrol, it means that there is nothing particularly wrong with your car. Infact, there is one Oxygen sensor installed in this model and when mechanics do the CNG installation, they mess with that sensor. So, the ECU is getting the signal that the mixture settings of air+cng is abnormal. That is why this light show up. There is no way to get it fixed, perhaps the interval of appearing this light can be variable but it should come if u have CNG installed. Also note down 2 pionts
1)if u r going on same speed and dont vary ur speed, it will not show up.
Rather check
2) whenever u refill CNG after that whenever u applying brakes the air mixture goes out of proportion for ECU and this check engine light glows up.
Once, my friend has the same issue with his I-DSI, and we tried everything to get it fixed, even we got it scanned from scanner, but it is just Oxygen sensor setting that is getting this light to glow up.

For confirmation, whenver u get this light on CNG, just turn off the switch and drive on petrol. If oxygen sensor is causing the issue, it should not come on petrol drive.

thanks buddy.....

[fahad_reloaded]

Its the trunk my friend....

yup, sorry my mistake

[sheikh_wah]

i also travel daily to islamabad for my job...

Me too :). 100 Km daily, 5 days/week.

no, the power window is not linked to throttle body in any way but its linked to battery. when u take the battery out, the AUTO system gets reset and now u ll have to set it back again. which is hardly a 5 second job.

Just operate the driver side window, roll it up to the max but keep the power window knob lifted (i.e. window pushing upwards even though its at the top) keep the button/knob pulled for about 5 seconds and it ll be done. now check if the auto system is working or not. it will...

ohoo, does it also apply to idsi 2005???

[fawadakbarkhan]

ohoo, does it also apply to idsi 2005???

every city it applies to my friend...!

+1

100% agreed. i ignore the check engine light almost all the times. it shows up every once in a while on CNG. infact its appearing more then even in my case these days probably because CNG kit is full of oil and needs cleaning. will get it done soon.

@3170
yes sir, it applies to all citys.

[Imaan1]

^ the mechanic said the same thing to me when it started appearing on cng .

[ahmadbila]

okay, here comes another DIY... infact this is around a month long DIY
I ripped out all the carpets of the trunk of my car, washed the carpets thoroughly and then put them away for many days. meanwhile, cleaned the trunk (pix few pages back) and decided to let it go without having the carpets fitted back. got to know how dust enters the trunk and fixed that. today, i cleaned it again, a few places with petrol as some engine oil was leaked from an oil bottle in the trunk. fitted the carpets back again.
here are the pix.

Awesome !

[huzaifaa]

Awesome !

no end results r even more then awsum
but ALLHUMDULILLAH mine is already in this condition

[Imaan1]

^ Yup, mine too

[ahmadbila]

to keep the carpet properly attached to the cng cylinder in a way to keep it hidden. i use this card board piece attached to the carpet (used samad bond to glue it) and then put double tape on it... this way, the carpet stays firmly at its place as in above pix.
