Bahi itne power ka kero ge kia? wase if you dont have O2 things may be other way around but not sure about that either. Because if you dont have O2 then ecu wont be able to tell if car is lean or rich. I think MAP manages it.........

Race lagane h? i have seen a car at workshop he had AEM ECU, F20B DOHC without air filter, no seats no doors and pata nahi kia kia , i thought if he was crazy like that he could have bought a sports car not ruin a 96 civic for that........

Allah bachae g race se : D
And it has o2

i met sabir at his motor vehicle A/C workshop [ your favourite NEEM ka darakht is still there opposite NUML university campus in North Nazimabad ] - this afternoon, 12 cars were lined up, honda suzuki toyotas and i had to take an appointment which is of Thursday April 23rd at 10.30 am.

i saw 8 vaccum pumps working on cars, 1 was filled up with ref.gas and owner was like. THAAND BHAR GAI gari mai .. !

He is very candid about ' Ham 1995 sai pehlay model ki koi gari nahi laytay ' thursday ko 1995 sai pehlay ki gari maat layeay ga., we had pleasant chat he invited me for lunch which was served during my 30 minute stay.
@Xulfiqar

odd rule --- lol

I think he mostly gets pissed off by the incredible jugaarbazi on A/C systems and lack of parts which are found in 95% of older cars.

Sir i need your help urgently..
I noticed the coolant was slowly decreasing on my car.. its around 9 months old and has 14.4k kms on the clock. I checked the coolant level yesterday as I do every Sunday(and all other fluids). I saw that the coolant was on the low mark.

Today morning i went and bought a bottle of premixed suzuki long life coolant. Thats the only thing specified in the manual.

Problem now-
Ill hunt down the cause of decreasing coolant later.
The coolant that i bought today to top up is dark blue. Not green like the one poured in from factory.

Im sure its authentic as ive bought it from suzuki 3s with all seals intact.

I just wanted to know if i can top it up without having both of them counteract each other?

Thanks in advance.

P.s i still havent filled it in

Hi friend. Yesterday i was on my bike going somewhere. 91 Honda CG 125 and it's having rust here and there. I parked somewhere. A guy approached me and said this product will remove rust from your bike easily. White powder was packed inside plastic bags. He showed me a little demonstration on my bike's rim which is having rust. He used a little water and that white powder. Rubbed for 4-5 seconds and the rust vanished. I was shocked! Then he applied that thing on the plastic indicator on my bike which is chrome plated and guess what the rust vanished again! He was asking 20-30 for one little bag of white powder. And the liquid he was using was water. When i asked him what is this liquid and it was water. He took a sip of it to show me that it's water. I wanted to buy few bags of powder but was confused. What was that white powder? It did wonders. I didn't buy it because i am not sure if it's safe for skin because i myself would have applied it. He told me he got it from Bolton market here in Karachi.

if its formulated the same then no need to worry, but for a glass full of top up in the expansion tank, fill it with distilled water. But as you now bought this and if its the same formulation then its probably ok to use.

Bhai my cousin bought a 1.5 tons air conditioner. Its a split type and is imported by the owner from Germany some 10 years ago.
Now the thing is it doesn't have the owner's manual with it and all the company stickers and gas charts have been washed away.
How can i charge the gas by weight in it??
The piping is 11 feet and outdoor is above the indoor.

Assalam o alaikom Xulfiqar bro

Bro i ve civic exi 2005 and i m facing a very strange issue.. car's front brake calipers have become loose. Due to this, brake pads rattle upon encountering any uneven surface or pothole etc.. i am astonished to its occurrence and want to seek permanent resolution please

[nasirjavaid]

Salam Xulfiqar bro.... need advise.....

Have Cultus 2007 VXR carby. My engine has started stalling and don't know what is the issue. It goes like on idle rpm drops to 400-500 for a second and then raises up to 1000 and then cycle goes again. Sometimes engine dies. Same happens while driving on low rpms while on high rpm it does not happen.

I washed its engine bay 2 weeks ago and covered distributor, coil, alternator etc...
Last week service station guy washed engine bay without covering anything. Although I told him not to wash it but still he did (that idiot)

But this issue I noticed before washing engine bay but then it was very minor and now worsening with time :(.

So any idea what could be wrong? Could this water spray shorted alternator or some other wiring is now wet and leaking current?

Thanks.

@xulfiqar

so apart from my this post i have a new question lol

i once read you saying the CNG out pipe - the one that goes to the engine - should not be more than 15 cm in length or it will cause combustion problems. Correct me if i am wrong.

The question is it not possible every time we install the CNG it that pipe gets a length of 15 cms. You know space problems installation problems and etc etc. So what should we do in those cases?
By the way i searched over the internet read CNG installation manuals they had stuff but no body talked about that pipe length i wonder why is that? May be its a good thing to be less than 15 cm but not as much important? Even my car has factory fitted CNG and in my case that pipe is not even near 15 cm - its 28 cms.
Plus a quick word about circulating hot water through the CNG regulator. As the hot water is taken from the car's cooling system so i guess the coolant can also be used for this purpose as i don't use water in my rad. Right?

[Xulfiqar]

15 inches in length, it would be impossible to mount a 15 cm pipe.

the hot water routing is necessary otherwise the regulator can freeze - make sure there is coolant in the system as a rusted regulator is expensive to replace.

[umair2203]

can you kindly tell me the difference between these two suspensions and how are they different in drive .. one spec sheet is of Corolla Altis 1.8 and the other spec sheet is of Corolla Gli 1.3

Suspension of Corolla Altis 1.8

Suspension of Corolla Gli 1.3

[umair2203]

.. one of them says independent type ^

[margallar]

check the plug wires and coil for arcing. btw the starting problem after wash is usually because the rubber seal of distributor cap has deteriorated. or water has gotten into plug wire boots
