Hi Dawn,

Have you pulled the spark plugs? If so, what did they look like? Black and sooty will likely mean you aren't having a fuel starvation problem. Have you checked the Mass Airflow Sensor (MAF)? Its just downstream from the air cleaner housing. When mine (88 trooper, 4ZE1) went bad- the fuel/air mixture was so screwed up that the truck ran like s#@t (like what you are describing) and it was so rich that when I popped the hood the exhaust was glowing red hot! Unplugging the electrical connector for the MAF should make it run better if the MAF is bad. The new part is.... brace yourself..... about $800 from a dealer. However, I was able to get one at a nearby junk yard for less than $50. In fact, I bought an extra one just in case this might happen again. Let me know if you need one and can't find it locally.
