    I have a issue you all might help with. Stated out with overheating, had a split along the top of the radiator. Changed it and the thermostats, oil and antifreeze. Testdrove and faulted on #6. Moved coil to #5 and faulted on #5 & #6. Moved it back, no fault. Testdrove and #4 faulted, moved coil to #3. It faulted 3 times, replaced the coil and testdrove it was fine. Got up to go into town and now it is faulting on #7. Anyone got any ideals

    Seems like random misfires on multiple cylinders. When was your last spark-plug change? Edit, also potentially bad timing belt?

    Changed timing chain at 200,000 miles. It now has 235,000. I guess when it overheated it really affected the coils, plugs are good but it came down to $. Had to change out all the coils at 640 dollars.
