Yesterday I decided it would be a good time to Seafoam my car and then change the oil. So I pulled the hose off of the PCV (car would barely stay alive at this point), stuck a straw on there and sucked in a little Seafoam. The car died. Then I started it up again and sucked in a little more and it died again. In total, I didn't use more than 1/8 of the can. So then I drive it to Strauss and grab some oil after letting it sit for a little bit. It was fairly normal. So then I got a case of Mobil 1 10w-30 and a quart of synthetic Lucas as well as a filter. I changed my oil and the car was running OK. Then later in the day, it can't hold an idle without stalling. It's been like that ever since. I tried taking the batt cable off and resetting the computer. It hasn't helped, I've had to drive around revving it at stoplights to keep it from stalling. What happened????
