i have a 2002 focus se with a auto trans 148k miles on it. the issue is when i start the car in the moarning it runs fine but if i drive it to the store and i go to restart it after its gotten warm it wont start or ideals funny and turns it self off. ive replaced the plug wires and air filter just for regular up keep on the car. the car has no check engine lights so im confused on what it could be i did take the throttle body off to clean it and noticed oil in the the air intake manafold so i cleaned it out . i am thinking maybe the pcv valve it causing all the issues im not sure tho if that would be it any help would be mutch appreciated im new to having a focus. thank you.
