Poor Acceleration, Bad Fuel Economy, Whats Wrong?

[shehbaz5959]

i used 2050 for first time GP oil and car has done 1300000 km is that ok?

1. get your transmission oil changed as well. Put in honda specific to be on safer side.
2. When was the last time you filled / serviced the AC system. please do that and check for proper quantity of AC refrigerant.
3. Also check your AC compressor for faults. As it is putting lot of load on the engine.
   you can try by just removing the AC compressor belt and drive the car for some time. if car runs good then your compressor is faulty.
4. Drain that 20w50 ASAP and if you want thicker oil anyway then use 10w40, i recommend ZIC x7. otherwise the brand is your choice but dont go beyond 10w40

irfan thanks for ur reply. ac was serviced last week. even if car runs well without AC how can i be sure that its the fault since doing any of above mentioned things fixes my issue for couple of days...but after 5 days car becomes heavy again.....thats true that when ac trips car becomes rockets for few seconds but without ac pick is bad too...i have to engage 4th gear at max 60....more noise less acceleration....last week my fuel pump failed so i put in chinese used pump and enjoyed my ride for 1 day only...car was weaightess and fast but now back again...same happened with tappet adjust few months back...shold i go for scanning when no check light is there...

[irfan44]

i hope your checklight works?
better to get the car scanned. i would recommend to get the catalytic converter checked first if your car has one.

[shehbaz5959]

no cc in my car..yes check light works....irritating smell from exhaust has some connection with picup?any mechanic u suggest around bahria town area?

From your posts, it appears that it had CNG earlier.
Please diligently scan the wiring of your car, primarily for MAP sensor and injectors. If there are any small pieces of wires joined for CNG, please remove those and directly connect original wiring.

Have experienced it on one of my cars. It used to give similar symptoms.

[shehbaz5959]

someone pointed me out as the ac blower is not giving a good through and said freezer is not workig fine making the car suffocated

[shehbaz5959]

hamza cng wiring was removed and injectors changed not sure though the changed one are working fine..no cng related thing in my car now....sudden pedal push causes mild jerks and delayed response..suggest a mechanic best in best of his work

[shehbaz5959]

even MAP is changed few times lets scan it first

Why are you using Caltex 20w50 i guess this is not recommended for VTI engine

5w-40 or 5w-30 is suitable

[shehbaz5959]

i tried it for first time previously i was using shell 1040w now i tried 20-50 i guess and its an exi

[alikhan7]

20-50 is very thick oil and suitable for motorcycles,old diesel engine and trucks.
who every recommended this is not your friend

[shery_leo]

can u tell me which engine oil is good for honda civic 95 i am also using 20.50w for my non efi engine

[alikhan7]

you should use semi synthetic 10w-40 or 15W,40 for better performance

[alikhan7]

If your engine is not too old 5W40 is best

[irfan44]

ive been using zic 10w40 in my 99 civic exi for 5 years and had superb performance. used 20w50 once and engine felt suffocated. switch to any good 10w40 semi synthetic. it will not reduce oil.

Get your clutch checked, could very well be a weak clutch and pressure plate

[shehbaz5959]

i remember few months back the mechanic opened up the filter and out came huge amount of mud and keechar..........the filter was re attached after cleaning.....the mechanic looked into tank by pulling the seat and taking pump and said tank is not dirty.....question is then where the mud is comng into filter then???can this issue be due to dirty fuel tank????i have tried 6 different chinese pumps new and used and problem re appear after few days such sluggishness of car and hesitaion to accelerate...i also need injector cleaning with it?

[dayrider]

Get your tank cleaned, get a new filter, and hopefully that should solve it
