Experts, I am trying to zero down on a problem shown by a Toyota 1NZ-FE engine at cold starts. Following is the background.
Engine: 1NZ-FE 1.5l YOM 2003 110k kms.
Air Filter: New
Tuning: Recently done
Throttle Body: Clean
MAF Sensor: Clean and ok
Plugs: Good
Fuel Consumption: Normal and Good
Engine Oil: Toyota, good condition
Overall: Well maintained
Fault Codes: No Fault Codes
Symptoms: "ONLY" on "some" cold starts, the engine revs to 2200 to 2400 RPM. And get settled after warm up.
Mind you this is NOT the usual engine warm up and self diagnostic routine, where RPM goes to 1800 and later settles. Please rule out that. This high RPM is beyond that.
And I detected a pattern after reviewing that this happens when and only car sits for more than 24 hours. If the car runs everyday and long distance, everything is ok.
Beyond this the user says at rare intervals and in traffic the engine try to go lower than 600 RPM and then kicks back. And this is rare.
I'm going to buy a car in SL for 2 mil while being in Germany. Then I'm going to put up a public raffle draw and pick one lucky winner to gift that car when I have 600 participants registered in the raffle draw. Registration fee for each participant is Rs. 5000/-
Why didnt I think of this before
So for a spirited convo like this old times; ?BYD
My father has gone ninja about getting one, despite being the new hype/fad here these are common across the world and I've seen a few cross 100,000km in Nepal and Australia.
Seal - Looks nice, very premium interior but too low for my applications
Sealion - Very Premium, feels very well built, BUT that 1.5L on that reasonable chunk of car with a measly 18KW battery seems like a recipe for trouble, incase they sink in value at least the fuel economy must justify that (They say it's a BYD engine - though the lore is it is a hyundai engine)
Atto 3 - Most sold from their lot apparently, common af, Seems to be the best bang for buck IMHO, Its electric since BYD is famed for that, Interior is kinda good, the thing is larger than a vezel but not too large like the Sealion, cheap mobility I guess with less things to go wrong
Dolphin, almost a smaller atto and again too car like and not suited for my application.
JK nailed it on the price and distribution but the only guaranteed thing here is the lot are gonna muck up the aftersales. The Kandy center staff behave like the crew from a Govt. post office.
What are your thoughts and opinions? Could this be the next Wagon R or is this a passing fad like the Micros of 2000s-2010s?
I have an empty parking slot at home previously occupied for 6 years by the starlet and 3 months by an AD wagon -what would be a bang-for-the-buck fun shitbox? Preferably auto as I live in a crowded suburb that has sapped the joy of stick shift out of my system.
