my car has a weird idle in the morning when it has been sitting.. i go to start it up and it starts no prob .. but after a few seconds or so it the rpms will drop down and hop back up and drop down again .. really weird.it goes away and runs fine when it warmed up .. and when i take off and the car is not warmed up it will kinda sputter .. so i floor it and then it sputters a lil more befoe it takes off like a bat out of hell and everything is fine..

not sure if this has anything to do with it .. but i unpluged the
MAS(well forgot to plug it back in) and the car idles fine during cold starts but but when you rev it it dosent rev smooth...
so i plugged it back and everythings fine .. but again the car had been warmed up ...
could it be my MAS going bad?
any ideas?

 

if you have a bov are you venting into the intake or atmosphere? and did you ever mess with your idle air screw?

 

when i got it it was venting to the atmosphere and the biss
screw was tamperd with .. but now everything is stock ..
well it recirculates and the biss is set @ 950 rpms @ idle
when ithe motors warm..

 

Isn't stock TEL idle 800?

 

i think its 750
but anyideas of what would cause this ??
its not that big a deal .. i just have to warm the engine for like a min before i take off .. but it gets annoying .... and id like to get it fixed

 

have you pulled any of the honeycombs out of the maf, and have you checked your spark plugs lately?

 

no all the honey comb is there .. ill chage the plugs tommorow but i think there fine

 

anyone else?

 

Sounds like you have a intake leak. I would put a leak tester on it. I have one and would do it for you but i live in bradenton.

 

i ws told it cold be a leak ...but i dont know wherer to look ...
can anyone in the pacso/hillborough* sp/pinellas are help me out ?
