Probably a shot it the dark, but if your computer reports no error codes
chances are your sensors are working correctly (again YMMV). My thoughts on the
next step would be to check each spark plug wire for breakage, or high resistance.
Then check each of your plugs. I had an incident that after I had an oil change
the truck ran lousy... I thought for sure that something internal had broken. It
turned out that 2-spark plug wires went bad!!! This was 1 hour after the oil
change!! Is that weird or what???! So it could happen, and it's worth a check
for piece of mind.
