My stepdaughters Saturn when in gear (auto) has a rough idle just above the point of stall. SES light is on. Codes at Autozone are PO133, PO442 and PO303. Car runs ok above idle (regular operation). If you take the car out of Rev. Or Drive and put in Park, the rpm's shoot abnormally high. At start up the rpm's also shoot up a bit but that may be a choke issue. As to the codes, I pulled the number 3 plug and it appears to be ok. She did purchase a new fuel cap. The hose from the cam cover to the air-intake had a split at the intake and I corrected that. It then ran mildly better at park idle but not while in gear. There are more options for repair than dollars. Any help on which direction to go would be appreciated. Thank you.
have the same problem?
