well i dont havemy emission stuff in my car...

the EGR and all that other stuff...

My problem whenever i start my car i always have to wait for 2 to 5 mins or so after starting my car up everytime...cus if i dont wait then the rpm will bogs down and stalls the car if ever the idle foes pretty low...whenver i step on the gas..

i already cleaned my MAF using a MAF cleaner..I changed my O2 sensor already...Changed my spark plugs and wires...also cleaned the Air intake line that goes to the throttle body...

my car still bogs down and still have to wait 2 to 5 mins before driving the car...

the car runs great after letting it idle for 2 to mins...

wheneveri donw wait then it will bog down and when im driving it chokes alot...

please help me...THANX!!!

your EGR needs to be open during cold operation aka open loop to warm up the car. until it starts to reach operational temps, its going to bog.

well how is the EGR being bypassed? how are the vacuum lines routed?

if they all tee off into one source of vacuum then yes that may be why.

BTW, i dont know if ill be able to work on your car as much as i could anymore since i have a new job now. either way i still want to get that money from the swap i did, so if you could replace the vacuum lines and sell the car then we're all good. i have your springs still.
