so i took my t67 off and threw my frineds stock t25 on there... ive probably put a good 200 miles on it and everything works fine...then i park my car over night and try and start it in the morning and it just sumbles off at idle unless i give it gas... once you get the car to start moving its ok, the only problem is when you are coasting in gear and then you go to get back on the gas it hesitates for about 2 seconds then drives ok...

the car randomly wont idle at all and its pissing me off

im pretty sure its not my maf.. could it be my fuel pump?

you could try unplugging your battery. your ecu might just be used to a different size turbo. Unplugging your battery resets it.

On my 240sx, I had a larger sized vacuum hose just in front of my pcv hose running into the intake in front of the throttle body. When that came loose the car would die out on me unless I kept the revs up. Check to see if any vacuum lines are undone or loose.

thats the IACV .. and its ok..

turned out my car wants to map based so bad it spit the maf extension off JUST enough so it would get a little bit of a readying, and not enough where i would see it

so i put everything back together and it runs fine now!

thanks alot tho guys.. +rep
