this issue was there in my ex ride though it used to run without any hiccups but I remember later on its gaskit gone bad and we had to change it. That carby car of mine was on cng so I always thought it is something to do with CNG.

Codes were pulled using a professional scanner; There was no code except misfire which has been fixed with Spark Plug replacement. I don't see a reason for compression testing as it seems irrelevant. How does a compression test result indicate reason for a rich fuel mixture?
I've gone through service history and car has been properly maintained with regular oil changes.

the black soot at exhaust indicates oil in fuel mixture. Thats' why compression test is suggested to ensure nothing as in rings or valve train is leaky

Sir i have bough it from a lady they had already 3 cars this one was parked mostly its a 5 grade car with verified auction sheet

pwuser160840527558 (Talha Khan) 2021-01-12 12:23:04 +0500 #11062

It still holds new car fragrance Alhamdulilah after alot of khuwaari of 3 4 months i found this i spend alot of money on getting cars inspected by pakwheels but all sellers were mostly dealers were liars they write something and when u check the car its in different condition its very hard to buy a used jdm car in good condition. I bought this one from direct owner Alhamdulilah satisfied with the price and condition of car. 1st owner on owners name with auction sheet i verified from pakwheels

Congrats on your purchase. Must be a good car as per your description.

But as a general observation, I have seen lady owners who don't know that car's oil needs to be changed after fixed intervals. They don't know what filters need replacement with oil. My lady doesn't even know from where is the hood opened (of any car).

pwuser160840527558 (Talha Khan) 2021-01-12 14:23:22 +0500 #11064

Bhai but this lady had very good knowledge about the car i was surprised to see she was explaining each and every thing like engine oil air filter routine maintenance she also recommended me the shop where she went for the oil changes she was very much in to it and very honest mashaAllah.

pwuser160840527558 (Talha Khan) 2021-01-12 14:25:17 +0500 #11065

a car that has been sitting for 5 years is not a good car in my opinion, Rubber parts rot faster when left sitting, lots of other issues also happen which are temperature related.

Dont fall for the "kam chali hui" - 6th, 7th or 17th car of household - its all a facade.

btw - anyone knows what an airfilter is and that cars require oil change and at 15K kms the car would be on its 2nd oil change and original air filter from factory - dont be impressed by such.

for your question.

The recommended viscosity for your engine is 0w20 and spec quality of oil is minimum of API SM for the life of the car - dont fall for "mota haail - sunn injann taqreer" from the shopowner. Toyota know far better as they designed and built the engine.

I have 1 pack of 4.54 Litre of Toyota Long Life coolant (Pink grade) which I bought and brought from KSA almost 4 to 5 years ago.

It was placed unopened in cupboard at Car corner of my house.
Can I use it in my car now; will it retain all physical and chemical properties same as it is written over pack or has it passed away its "shelf life" or "storage life" ?

@xulfiqar brother AoA is there anyway to check iridum or platinum spark plug with multimeter?? If yes then what reading shows good condition of spark plugs??
Thanks

Xulfiqar (Xulfiqar) 2021-01-13 20:39:30 +0500 #11072

There is no way to test it with DMM, as spark plugs operate at 25K volts. Best do visual check and measure gap very carefully and adjust appropriately. Their firing electrode is very brittle and can fracture very easily.

meaning if you need to increase the gap, you have to pull on the negative strap of the plug, do not try to wedge it open like old plugs - you will definitely break the electrode.
