All parts below where replaced. Some more than one time:
All four oxygen sensors (one was coding - failed - and was replaced a second time)
PCM (first replacement - reprogrammed twice, due to car would shake intermittently stopping at the stop light. Then replaced again due to check engine light)
both catalytic converters
Flow Valve
Other Parts:
pcv valve
Any ideas would be greatly appreciated!
An inexpensive code reader from Harbor Freight would be an invaluable tool to have.
