this sounds like ecu trouble. There is a power cable on the battery that can cause this problem if that cable is left unconnected. It happened to me when i swapped out a battery. car ran very rich like ecu was failing. fried three ecu in row before I found that cable was not connected. luckily the ecus are easily fixed. just look on the back of board to see if there is burned trace. if that is not the issue car would need to be here to be diagnosed further. this type of problem is not easily fixed on paper. dont expect much from people on these forums. it just makes you look bad.
