Cold Starts

[Guest RiceEtr]

Anyone here experience jerkiness when you first start your car in the morning? What could be wrong? It goes away after the temperature warms up alittle. It's annoying the shits outta me.

The problem you are having is that on colder mornings the computer uses the water temperature of the car to decide how much additional fuel to add to the engine, until the engine/water temperature is normal. I know that with the R33 there is some type of sensor on the plenum chamber that should compensate for the temperature, maybe your's is not working properly.

I have aftermarket management so I can fully adjust the amount of fuel added at cold start. If you don't have programmable managment then I'm not sure what the answer is, speak to a tuner, i.e. Steve at SST.

It's not going to do any harm but it can be annoying having a car that jerks and stalls in the morning.

i used to experience that problem when i used to own a lancer.

it can easily be solved by running some injector cleaner through the car. run this rich by using the injector cleaner in when theres hardly any fuel left.

another way i fixed the jerkiness of my car when starting it was by using high quality fuel. in this case i used BP Ultimate. maybe you're using cheap fuel? remember to always use high octane fuel. this will ensure your skyline will remain in good condition:)

Using it when your fuel is low?

That kinda defeats the purpose doesn't it?

When your on low the bottom of the tank is all gunk, so ur burning some contaminates, i can see by adding the injector cleaner mite of cleaned it , but doing that wouldn't make sense??

Am i wrong??

Actually I'm running on BP Ultimate. It only happens for about 5 minutes *the jerking*, before things start getting better.

Mine did exactly the same thing, if it was clogged injectors then it would do it all the time. I'm sure its just the cold start from your computer.

Mine's an R32. Does it have the temp compensation feature you mentioned earlier?

[adam 32]

it may also be your spark plugs. if they are the wrong heat rating (too cold) or are gapped close together OR are starting to foul then you will get a jerkiness on cold starts

btw what the hell is an R33 GTS-t VSPEC?

[GTS-t VSPEC]

My R33 has a VSPEC diff in it, that means it has both the traction control and Active LSD like that found in the VSPEC. These came from the Nissan factory like that, I know of only a couple other people in Aus. with them. The Active LSD is really cool for high speed cornering.

Now that would be a pretty awesome and rare car.

Coming back to my question, do any of you think it's got to do with fuel mixture content (too rich or too lean) or anything to do with the Air Flow meter?

[Ait]

I've got the same bloody problem too! I can't figure out why! I've been told that it's just cold and that's it!

[kabab]

yeah my car does that to i just let it idle for 5min...

[Ait]

Do the 33s encounter a similar problem too?

[BuzLightyear]

Mine does it too - just till things warm up. Gives it a bit of character, eh.

I had the same problem, though it pretty much went away since cleaning my afm and resetting the ecu...also the fact my car will be at the shops for a few months has cleared the problem

On the upside, im finding large amounts of $$ in my bank account since my car hasn't been around...
