I have a 2000 Ford Taurus. 3.0L (Flex fuel). Yesterday, I noticed the car developed a small miss, & the check engine light came on "steady". When I ran my OBDII, I received a code indicating that a Cylinder 1 misfire was registering. So, I went to the parts store, purchased 6 Autolite plugs, & a set of Autolite plug wires. After some work, thee new plugs, & wires were installed. Upon starting the car, it appeared to idle smooth. Upon the test drive, the car was shuddering / hesitating, with small misses & very small backfires, and the check engine light is now blinking. So, again I put the OBDII on the car, & this time, I received codes for misfires in Cylinders 1 & 2. Winter is coming, I have spent a small fortune on new waterpump, rack & pinion, heater core, serp belt, air cleaner, thermostat, & more to get the car ready for my family. I have gone through too much in the last week to not have this car work. Please help me.
