Thread: Wont start when its warm

so my car wont start when its warmed up. from a cold start it is perfect. the car will sometimes stall at idle especially if i pop it into neutral after being on the highway. it gets a little rough at about 2500rpms. the temperature gadge jumps alot when the car isnt warm yet. i have checked all spark, air and fuel. its all good. ive came to the conclusion it is a sensor somewhere. I cleaned my maf and it looks fine, replaced my TPS, ive also replaced my PCV valve. any idea on what else it could be?

lol you came to the conclusion, but have no idea eh?


check your temp sensors, theres 2.. one for the gauge an one for the ecu

any idea where they are located. i have a sr20de longblock.

they are located on the intake manifold on the pulley side of the engine..

it kinda sounds like you have more then one problem tho..

i found one temp sensor right under the intake manifold on the pully side. but i cant find the other.

they're right next to eachother, one is a 1 wire the other is a 2

check out the FSM, it will show you nice diagrams as well as test procedures. You can find it in the FSM thread that is sticky in this section.

ill look at it in the light tommorow. i was usuing an ipod for light

thanks
