[cooldevil]

halo guys! i want to swap D15B7 or D13B4 in my city 2002! i will use cng as i want a good economy! currently my stock ff engine gives 180km mileage in city in 550rs of cng! problem i am facing is that the car does missing on petrol because its camshaft needs replacment or may be the engine needs to be overhuled! On cng it runs flawlessly! what should i do? plz tell me the prices of the engines and give me suggestion that whether i should overhaul my current engine or should i swap it!looking forward to your feedback!thanks:)

[qaswah]

[cooldevil]

haha! i showed my car at honda pit stop rawalpindi! i told them that my car is doing missing,no pickup and rpm is unstable! they did tuning ,tappet adjustment, plug cleaning, throttle body service, air filter change etc! as a result car baceame awesome on cng but on petrol is was still thje same rather it become worse! now they are suggesting that my cars engine is weak and its engine needs overhauling! camshaft is not working properly!

Your problem is not with the camshaft. Please refrain from getting any engine head work being done, your problem is totally pointing in the other direction.

Get your Fuel Injectors checked, there's a bright chance they might be clogged.
Your Fuel Filter will need replacement as well.
Your Fuel Injector Rail will need to be replaced too.

This happens when you drive on CNG while there's little Petrol in the car tank. When you switch to Petrol, the deposits in the tank then clog the fuel lines and eventually the injectors.

You will get a set of Kabli injectors from Shershah for around 4k, try finding good ones and get them checked before buying, this is very important !

Get a brand new fuel filter when you get this done
Better get this done as soon as possible because your car starts on Petrol and THEN converts to CNG, if the condition of the injectors gets worse, you'll have more problems.

If you can afford brand new injectors, that would be the best solution since Kabli injectors are just temporary and won't last you as long.

Hopefully this will help you, keep us updated

I have also had similar problem on my idsi. Those honda theives that your engine is finished will need a complete everhaul this and that. Car was as smooth as butter on CNG. Tried my luck went to a new mechanic who claimed to be an efi specialist and returned from dubai. by the name of allah i started. The situation was so worse on petrol that the car could not go beyond 500 rpm and continuous missing. he changed the injectors, there was some problem in emmulator as well so rectified that too and cleaned the fuel filter and checked the fuel pump its alright. When the car started on petrol it was wonder. Car was as smooth as butter better than CNG and idling on 750 rpm. No the pick is awesome and car drips more water than it used to do in morning. Ride has also improved on CNG but on petrol its awesome. So better get these things checked if the problem persists than you can go for engine work

Thanks, it's a common problem, mechanics are misguiding everyone.

To prevent this from happening again, keep your tank at least at the 40 Litre mark. Use PSO Petrol. Problem won't happen again anytime soon

[cooldevil]

thanks alot guys! i pray to GOD that my cars original engine becomes fine again :)! will try your suggestions and will update the thread! once again thanks @rohaansaeed @a_n_memon88 and @mahmood

[cooldevil]

btw does anyone know the price of OEM injectors?

[aantherax]

the problem you are facing is related to fuel injectors

[aantherax]

i had this issue in my City Exi-s in 2010 i went to honda they told me to replace the injector and quoted me a price of 18000 Rs i wasn't satisfied i went to another honda 3S they told me first we will try servicing your current injectors let us do it i agreed they serviced the injectors and in 2 hours of time car was back to normal ... and rohan is right when this happened to me my tank only had 4 or 5 liters of petrol ....

[rohaansaeed]

You will get brand new original Injectors for around 12k, at least that's the price in Karachi.

But in Islamabad it might be different, however, if you go to 3S dealerships, they'll quote you a lot more.

Kabli one's range from 3k to 5k

Do update us after you've tried changing them

[cooldevil]

one more thing i forgot to tell is that when the mechanic pulled the race upto 5 6 k rpm,the engine produced a little noise and he told that its the nosise coming from the crank! however ill going to change the injectors ASAP! thanks for the advice @ aantherax

[aantherax]

here is where i went for my issue ... just visit once may be you might not need new injectors but make sure you go there no later then 10 : 00am other wise they wont take your ride .... on the road from Eid Gah Nazimabad to shershah there is a PSO petrol pump on right hand side right beside that pump there is HONDA SAEED AUTOS (its a honda pit stop) just go there and meet MR. Saeed he is the owner and explain your problem I am sure he'll have your ride fixed

sir i live in rawalpindi

These stupid mechanics term any noise coming from engine to bad crankshaft. One of the mechanics + 2 honda 3s dealers have told me that your engine is done blah blah. Dear friend if engine has any issues they would amplify and the car would do more problems on CNG than on petrol that is why when the engine is overhauled first its set on petrol than they test it on CNG because a weaker engine would never be troublefree on CNG. If the crankshaft has any noise than it should not perform well if the crankshaft can move at 5-6 k rpm than I dont think there is any problem with the crankshaft because if there had been any problem it would have made crank heavier than normal putting more load on engine so engine would never rev upto its maximum rpms. If an engine with a bad crank can rev upto 6000 rpm than an engine with a good crank should rev at 8000 rpm and which is not possible. So I would further say that check any parts that are solely used on petrol i,e injectors, fuel rail, pump, filter also get ecu checked it may have some error or fault get it repaired

[cooldevil]

ur advice is highly appreciated

[cooldevil]

UPDATE GUYS : got my cars ica valve, injector rail , fuel injectors and fuel pump changed and now my D13b hyper-valve is acting like a BEAST :D! thanks alot guys for ur valuable suggestions! i would have gone for an engine swap or would rather sell the car! i m so happy bought all this stuff in 4.5k except fuel filter! fuel filter costs 600rs!

[rohaansaeed]

Congratulations, glad to have solved your problem

Get the fuel filter as well, 600rs is worth it otherwise you'll be in the same situation again soon

Did you buy Kabli parts?

4.5k is a very good price

[mahmood]

congrats bro and yes detail on injectors is required, kabuli or new, if kabuli then did you bench tested before installaion???????????
