I know I should let it warm up before I go drive it but, sometimes I just dont have time, ya know? When I crank it up and go, it kinda stutters for a second and then acts like I sprayed it. Does anybody have any idea what might be causing this? Any help would be great! Thanks guys!

 

Actually you should drive it from a cold start, just not hard. Letting your car sit and warm up is bad for the engine.

No idea about the jerking though...

 

really..? letting your car warm by just sitting is bad for the car? i guess i should stop doing that.

That's interesting. Out of pure curiosity, what is the logic behind this statement? Also, do you have access to any published material with supporting information? I'd like to read it.

 

so would i????

don't believe everything that you read

 

y wouldnt you want to warm up ur car??? its proper to start your car then let it idle for a few minutes to get the oil moving around and the engine up to operating tempeture, esp if you have a vtec engine, vtec will not kick in unless its warmed up to the proper temp.

id also like to see some proven facts that its better to start your car and drive it right away cold???? doesnt sound like a good idea to me

 

Ok, I have a problem with my car. Please dont let one DUMBASS get everybody off subject. I mean, a statement like that doesnt even deserve to be entertained. Its easily one of the stupidest things i've ever heard. If it were bad for your car..... think about it! That means idling is also bad for your car! You f**kin jackass! Lets all sit at redlights and rev up cause its better for the motor! Please do us all a favor and never post anything ever again! We are all a little more dumb now having read your incoherent nonsense! Now that i've gotten that out of the way... anybody know whats going on with my car? Thanks.

 

hahaha wack statement but i have the same problem with my teg jerking and jumping when i go to school in the morning

 

wow. that was intense. does this only happen when you "just don't have time" to let it warm up?

You'd be hard pressed to find the converse published information as well.

He probably meant to say that it uses more fuel and pollutes more to let the car warm than to drive it cold. In winter, I could let my car sit for 20 minutes idleing before the temperature gauge will move. (My '97 GSR that I have owned since it was new has always been like this.) I drive mine easy when cold and I'll have heat in about 3 miles and a warm catalyst to minimize polution. My warm up time is about 30 seconds which is enough time to get the oil flowing.

To the OP, what engine and ECU are you running? (Why does everyone assume that we know every detail about their car?) Is this a hesitation or actual jerking of the drivetrain?

 

My DA jerks in 1st when cold, Prob cause its so low of a gear and if I let off the engine slows me down. And if it is truely your engine jerking I would have to take a guess that its not burning fuel right or getting the right amount?

I know im prob wrong but its not hard to check fuel pressure, injectors and spark plugs.

(If if you are ggetting fuel wrong time too much, it is possible to dilute the oil of the cycl walls and that can be bad)

 

Mine does too, only when its cold out, and just started, but only n first. But once its warmed up its fine

and clover, i stole your thing in your prof...i like it lol

 

Sorry about that. I forget sometimes to be specific about my car. Its a 96 LS B18B. It almost feels like the engine is missing for about 1 minute and then it goes away after it warms up. Thanks.

Read a book for your facts. You dont warm up modern EFI cars. There's no need to. You drive them gently after a few SECONDS of idling, then drive them normally when they reach operating temp. Neither way is BAD for the car or GOOD for the car. Leaving your car running wastes gas and at best, hurts the environment more. It's purely a comfort thing.

Sorry to get off topic. This happens to my GSR sometimes when its super illinois cold. My people are a tropical people. Anyway, Your car is just running rich (normal in cold, openloop operation). Your culprit is probably an IAC (idle air controller) that is "sticky" from being carboned up. This means that not enough air is being introduced into the intake manifold to support the amount of fuel in there. Spray in some sensor safe Throttle body cleaner, into your IAC hole, and if you want, take off your IAC and spray it down. Dont take off the hoses, just take it off the intake mani, and spray as you hold it. and you should be good to go. If not, try changing IACs. They're relatively cheap used at about 20-30bucks. This is if your car's manual. Not sure if automatics have an IAC.

BTW, excessive idling isnt that great for your car. It builds carbon because of low velocity of intake/exhaust gasses. Oil also does not do a great job at idle. There are other reasons as well. Too busy to get into it right now. You shouldnt have been so harsh to that guy, huh? Like i said above, read a book, guys. Especially before you go on a crazy rant.

Open mouth, insert foot. LOL. jk jk

 

i thought it was awfully harsh on your car if you run it cold. cause its just like a person sprinting in a competition without streching

 

mine does the same thing, maybe its because the tires are cold or something i dont know. i dont think its a major problem though.

but in the manual for your car it says that warming up is not necessary.

Well....you warm up by walking, right? Stretching is like starting up....so you stretch for a couple of seconds. Then you walk, and you're fully warmed up. Anyway, Cars are not like people, but i get what you're saying. You definitely shouldnt BEAT on your car when its cold. Like i said, drive gently, then when it warms up, drive as you normally would. If its SUPER freaking cold, i guess give it a couple of mins just because there are rubber seals in there as well. But anything more than like 1-2 min is overkill in any weather. Unless you live in antarctica. Then you should ....iduno...move, and never go to antarctica ever again.

 

Just to play devil's advocate, when your in heavy traffic, you car can sit and idle for 10 minutes at a time, then move 20 yards, and sit and idle for another 5. They are made to handle it. It doesn't hurt the car to idle (within reason), and it doesn't hurt to gently drive right off the bat. Just don't jump into it while its cold and hammer it, and try not to idle it more than 15 min or so, shut it off instead.

 

I use to start up my car and go all of the time when it was cold out .. didnt last long untill i spun a bearing and i bet ya cuz the car wasnt warmed up . Just put a new motor in it and let it warm up like 5 mins than drive slow for the frist couple of miles .. Just my thoughts !

 

Carbon buildup. Dont believe me? Idle your car for an hour. Then you will have a bigger problem than what you have now.

 

I slept in my car on the side of the road one night and left the car running the whole night. That car never gave me one problem. But anyway. I recently cleaned my IAC to get rid of a rough idle. The jerking was happening before I did that and it hasnt gotten any better. So its probably not that... is there anything else you guys can think of that might be causing this.

 

weak distributor maybe. check Spark plugs. check Plug wires. The demand on those is higher when the car is cold.
