i need some assistance with a proublem i have a 95 Z34 with a 3.4 V6 the problem is in the mornings it is cold the car starts and goes to about 2400 rpm and then down and dies. After a few times it it stays running but barrely and when it warms up it runs just fine. well a little rough not any thing to worry about if some one has any ideas to my problem that would be GREAT

 

Check for codes

 

i just checked the codes and it had nothing in there but a oxegen senser i cleared it but it still would run then die untill it warmed up then it ran fine some one told me it mite be a vacum leek what do you guys think

 

Very possible a vaccum leak, also just gor fun, run some drygas through the tank and some permium fuel..cant hurt anything and your monte will love you for it.

 

I am thinking perhaps Throttle body issue... maybe the Idle Air Control Valve...?

If it starts up, and THEN dies, that means the engine is being choked from one of THREE things
Air
Fuel
Spark

So, that being said, change your fuel filter.. If that doesn't work...

Does your engine make any funny noises? Perhaps a really loud air sucking sound?

Just an idea...

 

Correct me if I am wrong but if it has a vacuum leak, shouldint the idel be sparatic. What I mean is jumpy.

 

thank you guys for the info i will tri all of those things and let you guys know what i found thank all of you very much

 

i replaced the idle control valve and it does the same thing could it be maf sencer
