Has anyone have this problem.......
 

I have a March 2013 build Toyota 86. Has 5500kms (3400 miles), had a oil and oil filter change at 2000kms with Mobil 1 5w30. Always filled up with BP ultimate 98RON (93AKI)

Recently, the weather here in Sydney Australia has been a bit chilly. About 10 degrees celsius on a 6am morning. I find the car takes quite a long time to start up. On a cold start, it takes a good 5 seconds for the car to start up. On a warm start, it starts instantly. This happens all the time on a cold start.

My girlfriend's 86 is a April 2012 build has 18000kms, has had two services with 0w20 castro Oil, very occasionally has the idle dip problem, but always starts immediately on a cold start. She only has a K&N filter in hers.

I have a takeda intake, Borla UEL and Unichip.

Is this to be of any concern?

EDIT: I have taken out the unichip. Still has the same problem. I press the start button twice to on mode, leave for 10 secs, clutch in press button... still takes 5 secs to crank up.

Will take it to the dealer soon.

EDIT 2: Mechanic and the dealer service centre says he is baffled. Everything is fine. It looks like they are going to lift the engine to look at spark plugs and ignition coils. If they are going to look at the spark plugs, i will be asking them to change the spark plugs to iridium NGK while they at it. Luckily, i only live 15 mins walk away from the dealer.

Funny thing was that the dealer was going to deny warranty since i had an intake and headers (took the unichip off) and i said "you gotta be joking me, intake and headers have absolutely nothing to do with this" and she says "i was joking, dont have to be angry about it". LOL

Any other suggestions what it may be before I take her in this Sat?

Perhaps something isn't quite right but I don't know that it's a problem. I seldom see cold weather where I live so an instant start is always my norm.

It's on a chilly morning start that the "0w" mentioned in the "0w20 ONLY" warning on the filler cap makes the most sense... I am guessing that deep down you're already thinking it: yes, you should flush your 5w30 and get some 0w20.

Yeap, this is rather common knowledge now.

I had a oil change 3000kms ago. It should have had this problem earlier then. Synthetic oil is synthetic oil, it will flow quickly. 5w30 can even start well below 0 degrees celsius.

I do 5w30 because it has a higher load rating than 0w20.

"....Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when
the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions....."

Manual for FRS and BRZ

I had Mobil 1 5w30 in my 370z and it would start instantly in snowy weather lower than 0 degrees celsius. I dont think the oil can be the culprit...

Yes, it can be. Especially if Toyota mandates it for the 86.

There's many threads about oil definitely should ask in there. Save the trouble here a thread for your kind of oil.

For the idle dip. Should search it I know I read some owners having the idle dip fluctuating up and down. I forgot what they did after. Good luck

Because you clearly know more than the Toyota/Subaru engineers. Especially when yours isn't working right... :slap:

Only way to figure it out is to start changing things one a time until it doesn't do it anymore. Maybe you should start by changing your oil....

like others said, i am assuming its oil

It's not the oil.

I'd blame the Unichip and/or the intake first. Or, there is an actual problem. Put 5W30 into your girlfriends car and nothing will change.

10 C (50F) isn't even cold.

This.

What should i look for in the unichip and/or intake that may cause the problem?

The intake is installed properly, all bolts screwed tight.

The unichip is installed properly, all the wiring put into the correct sensors. I have the takeda intake map on with Premium 92 octane Fuel - Timing + map (most aggressive fuel map)

I get this in warm weather sometimes.. a few weeks ago it cranked away all by itself until it decided to stop. Next push of the button it started right up. :shrug: no idea. There are some other threads about that issue.

Oh and I agree, it's not the oil.

put ur key in, turn to on (don't start the engine), wait for 5-10 seconds then turn the engine on. I started doing this, and haven't had long start since (maybe just the weathers getting warmer here :-)

I've done the exact same thing as mentioned above and I haven't had anymore problems.

It's normal for the car to take a bit longer to start when it's cold out, but in your case, I would attribute the the extended start time to the unichip, like a few others have mentioned. We're not talking about freezing temperatures here, so your oil is just fine.

Problem still there, after taking off unichip. Thinking about selling unichip to get ecutek stg 2

i had those problems too, (my car is made in march) the problems just disappeared at 20k miles for no reason... lol

OK hopefully will disappear with more driving.

Booked in for a check up at dealer on Wed

I've got 10,000km on my car, picked up in feb only 12km.. I have had an oil change from Toyota at about 2k and I have an injen CAI intake (which has supposed problems) and an injen SES exhaust. My car is parked outside most days in the cold, 7 degrees avg. and I have had no problems and an instant start. I don't believe it's the mods fault, but in saying that I don't know what my oil is...

Yeah its weird... Whats even weirder, say i park in a shopping centre and leave the car for 2-3 hours. And i come back to start the car, it still takes pretty long to start the car (roughly 2-3 secs) but not as long as it takes to start it when its a cold start in the morning (5-6 secs).

I park in a garage. Gets to around 10 degrees on a cold morning. Your oil will be 0w20. All Toyota dealers service with either Toyota Genuine 0w20 oil or Castro 0w20. I changed the oil to 5w30 myself with a Subaru oil filter.

I have started a GT86 in below -15°C many times and it was almost instant every time.
What you're describing is definitely something wrong.

Sometimes the variable valve timing system needs to be "reset" for a cold start.. So oil needs to circulate and pressurize the system for it to function properly and be in the right position for a cold startup, since it was elsewhere when it was shut down warm. You might be experiencing this delay. If the oil is thicker, it could also take longer to actuate the solenoid(s). But I agree.. Should not be the oil as 5w is thin enough. I experienced this delay at times with VANOS in my M3 and this system is hydraulically activated too..

Mechanic and the dealer service centre says he is baffled. Everything is fine. It looks like they are going to lift the engine to look at spark plugs and ignition coils. If they are going to look at the spark plugs, i will be asking them to change the spark plugs to iridium NGK while they at it. Luckily, i only live 15 mins walk away from the dealer

Yes i do know more than the Toyota/Subaru engineers since it is scientifically tested that 5w30 oil can start a car instantly in weathers as low as -25 degrees celsius. Learn about engine oil first before suggesting others to change their oil :slap:

Mine did that once. Hopefully it will not happen again. Strange thing is that the motor was actually warm. So i am assuming it is the starter or the wiring is somewhat faulty from the factory.

I had a few hard and non starts this winter when it dipped below freezing, started turning the car on and waiting for my Valentine One to finish its startup sequence before starting the car and never had another problem.

The ignition coils and spark plugs got changed. And the car now starts instantly on a cold start. I think im the first 86 in australia to have the spark plugs changed :lol:
