Just bought an 88 lebaron 2.2 t1 hardtop. Car only has a little over 100,000 and this thing has really been well taken care of. The lady that owned it said that it would not pass emission testing and that she was tired of spending money on it. When you start it cold it idles perfect but just as soon as it warms up a little it starts loping and the idle slows down to about 600 rpm. It did have a head gasket replaced not too long ago and I am wondering if the mechanic got the timming lined up right. It does act just a little sluggish on accelleration as well. I did unplug the map and when the computer went into limp the loping stopped but idle would increase and decrease back and fourth. Anyone had this condition before?????
