warming up

[ET pulsar]

hey just wonderin if anyone knows why my car needs to be reved up/warmed up for around 3 mins before driving. if i dont warm it up the car just cuts out and when driving it cold the turbo just starts spooling up radimly. The previous owner put v8 coils in it and ive heard this could be my problem or somethin to do with my ecu. anyone have any answers as to how to fix this or is it just because the car has an old engine. thanks.

well look at it this way... if your car is a bit older and had a lower compression, when you start it up cold, its going to run, but not well. when the heat expands the metal, the clearences all become reduced so therefor more compression.. and hence, easier running.

and as for a turbo spooling up randomly, is the engine revving randomly to cause the spoolup??

as for fixing the problems, maybe a slightly heavier weight oil, or just start it up, give it 30 secs to get the oil flowing, then just drive gently, if u know its gonna cut out, give it some revs..

na man like you cant just drive it normally if you dont warm it up properly once you get to like 3000rpm the revs like slow down and the car starts hopping its fukin annoying to drive you have to change in early rpm. if you warm it up its fine but its inconvenience like 5 mins sometimes there must be a way to fix it im gonna be replacing my coils soon i heard that would be the main thing that could be effecting it .

its cos its an old style engine...u cant really do much about it but trust its best to let it warm up if u wanna own it for a while...cos other wise it will die an untimely death(trust me ive seen it.) i cant see the coils doin anything.

how long do you warm your et up for man cause mine seems to be like way to long like its stupid how long you have to warm it up for. if you turn your car on straight out and let it idal will yours cut out or run without you revin it up on the accelerator. mine you have to sit on the accelerator. is there anythin that i can replace that wil make it run better . thanks

Forgive my ignorance, but I'm not familiar with the ET Pulsar... Is it Electronic Fuel Injected (quick search... it appears so)? If so, the car should not require warming up to the extent that you seem to be describing. I would personally be looking for a faulty temperature sensor, as it sounds like the ECU is trying to run the car without the fuel enrichment that is needed while the engine is cold.

EDIT: After reading a little about the ET on Autospeed.com, it appears that there should be an air temperature sensor. I'm not too sure where that might be located, though it may have been fitted in the airbox. If you have ditched the air-box and put a pod filter on, that may be your problem.

true thanks for the info yer i have my pod filter on and its relocated down under the front lip of the car.

i dont know if im just a retard for thinking this, but Ive always been in the habit of warming my cars up, regardless of how its running. 2-3 minutes of your life every morning is SFA, esepcially when you consider how good it is for the engine long term.

alrighty then thanks for your help i guess ill just be warming my car up thanks

yeh, i have to warm my 87 p.o.s bulk :squint:

this has all the information about why my car is experienceing this problem so if any one else's is doin the same read up on this shit.

i duno if this is simililar but my Exa runs pretty good cold and then once it warms up it chucks it in and will die if i try and accelarate at any decent rate, although it can handle it if i keep my speed steady with no serious load, ie hills. Ive recently installed a pod filter, will that matter.

[ET pulsar]

only if your cold idle sensors are in your standard airbox which your will be seeing you have the same e15 engine as mine youll just find youll have to warm your car up until it will idle by itself. if you dont do it your car wont rev out anyharder than 3000rpm so make sure you warm it up propery. just keep the standard box so you can get the idle sensors out of it and get a new box and place the sensors in the new box that may work im not sure.

[ET pulsar]

sounds like your waste gate is fuked anyway with the whole dieing thing when you accelerate to hard

[Panda_ET]

nah it maybe ur comp plugs? wastgate is easy to diagnose does it boost more than 2psi? does it jerk about?? the idle sensors arent in the airbox? they are in the crossover log that sits over the injectors and there are plenty of eays ways to fix that.

[disturrrbed]

cool thanks guys, well my standard air box, doesn't seem to have the cold idle sensors as it had nothing mechanical in there (i'm not too flash with cars), yeah it can boost more than 2psi. it does jerk about a lot when i put my foot down, it also backfires if i put my foot DOWN. it does not seem to matter how many revs i do but rather how much load its under

EDIT: the engine is a e15et

[disturrrbed]

well i checked the computer and it came up with

- car speed sensor
- Idle switch
- and another option wich had both of "Air cond. (with nissan air cond.)"/ "o.k (without nissan air cond.)" i dont think this should matter, so disregard the air cond thing,

i also reset the computer with the old air box in, and ill see if it makes a difference later

[Panda_ET]

With all those errors it may be ur comp if not then i would say wiring cos thats an awful lot of errors at one time...seems unlikely to all be a prob so id be lookin at the plug closest to the trans tunnel. I have been told that haltech use the exact same plug so u can rewire it if need be.

i been told by someone thats where the idle sensors are my bad

ok kewl was just tryin to help
