on a COLD start my car will turn right on then it will turn right off. any ideas why?

if i take a vacum line off, the car won't turn off, it will stay on.

when the car is warm, the car is just fine. i can turn it off and turn it on and it won't turn off. i'm noticing this on cold starts.

i changed the temp sensor on the head already, made sure all my grounds were getting good connection also.

any ideas?

 

longshot but it might be your IACV

 

nah...i already replaced that with one that i knew was working fine.

 

hmmmm
maybe your MAP sensor is going bad

and if it is bad and you need one i have one i will sell you for cheap

 

i have another one of those laying around. maybe i will switch them and see what happens.
