Something is not well w/ my burb! She ran fine last night, this morning i go start her, to let her warm up for 15 min, come back, put it in gear , and she feels like she is running on four cyl. I get it aroun the block, and she is buckin and lurchin. The check engine light comes on, so i shut her down, start her up again, no check engine light. She won,t idle in gear, idles rough in park. Last night was the coldest night we have had for awhile. I have a 95% full tank? Does anyone have any ideas? TIA.
