98 Contour
CEG'er
Hello all, this is a great forum, lots of good info!
I have a 98 Contour, 2.5 MTX, 71,000 miles, with a recent tuneup (plugs & wires). CEL is on, throwing a P1151 code. After searching the forum, I've narrowed this to three most-likely possibilities:
-bad bank 2 O2 sensor
-vacuum leak
-possible problem with the IAC valve.
In addition, the car "mooses" in cold weather, and tries to stall when it's been run for a while (usually over 1/2 an hour).
Before I start replacing things, I figured I would ask here to see if this is a common problem or if there is anything else I should be checking. Any help is appreciated. Thanks!
Chris
