i don't know if this is serious but now sense its getting pretty cold out whenever i start my car in the morning it revs up to 1500 rpm ... sometimes 2000 rpm. i've changed a shit load of shit ... sensor wise.

 

when i say sensors i mean maf, map, tps, its got a basic tune up.

 

i am really tired of thinking i know everything but that was/is my first mistake.

 

If anyone can tell me what my problem might be... It would be nice.

sorry i just got back from a 13 hour trip with my parents ...

 

she was very choppy too when i started her...

 

tired as hell... just brought the girl over to her house to setup some shit (she went with me) ... her mom just got high speed and wanted help setting up some wireless shit for her daughter (my girlfriend) ...

 

very cranky... etc.

like i said ... i'm tired cranky and dumb.

 

dumb is a 24/7 thing though :-)

my Euro and Z34 both used to do that when I first started them up on cold days, I think it's pretty normal

Yeah, if its real cold it'll idle up to around 1500 or so then slowly back itself down. Like a carb'd car does, cept you cant tap the gas and make it come down

well it just says that way ... even when i have it in gear...

 

it doesn't subside until i turn the car off... and restart it

i wouldn't be putting the car into gear at 2000 rpm

 

helpful.

 

all i know ... is when she's shutoff and reset she idles fine.

 

or when she's into gear and you press brake to floor it goes down too...

 

if it were a vacuum leak wouldn't it be there ALL the time?!

You could try doing an Idle Relearn. I know that my 88 regal does that when it's cold out. As soon as it starts, it'll go up to 1800 rpm, then agter about a minute, it'll come down to about 1000 rpm.

Does it ever stall?

Sounds like a leaky intake manifold gasket. Try spraying carb cleaner at the gasket and see if you can hear/feel any change in RPM. If yes, your gasket is shot.

Twas what I was gonna say. My Z34 would rev to the limiter on cold mornings, then when it warmed up it was fine. Fun thing dropping into drive at 2500 rpms. Check the intake gaskets.

Hasn't yet.

 

Thing that really aggrivates me is that it was changed a year or so ago... but then I've put about 50k on her since. Good grief :lol:

 

Its a sad yet freaky thing.
