Hi, I have a 93 chevy lumina she only has 91k and for about a month I have had a loss of aceleration. I changed fuel filters,sensors,plugs and wires; nothing worked. It can run normal for a while and then started running rough. it has never stalled. never run hot, but idle rough and acelerations slow. then all of the sudden bam power boost and run normal for a while then back to thr rough idle. been to three different shops and no one can figure out what it is. Any suggests?
