I have a 1993 100s 2.8 v6 5speed manual trans 114,000 miles. It suddenly started running very rich . spark plugs on left bank are dry and look normal,spark plugs on right bank are gas soaked.any Ideas would be appreciated. Thanks

 

To start, I would go through and clean and inspect injectors, and electric plugs going to those injectors, and your mass airflow sensor to see if there is clogging. If this doesn't work, check the millions of vacum lines,and replace any that seem to be broken or sweating.Lastly, does the idle surge a lot or not at all?
