Did tune up on my 91 ford f150 302 5.0L V8 4x4 pick up which included s[ark plugs and wires, cap and rotor, oil change, new oil and air filters...now it is riding rougher and worse gas mileage than before?...


did you properly "gap" the spark plugs? many spark plugs have to have the ends properly "gapped" before installation, by using a "gapping" tool/wheel to properly space the arc gap to the correct distance.

if the plugs were properly gapped, or already came pre-gapped out of the box for your specific vehicle, then you may have air getting into the cylinders around the spark plugs. were you careful to properly tighten the spark plugs straightly into place, or is there a chance that you left one loose, or, even worse, cross-threaded one of the spark plugs?

Need do know the spark plugs gap


If you're replacing the spark plugs in your car engine, you'll need to set the gap before reseating the spark plug. The gap is the distance electricity arcs between the ground electrode and center electrode. The gap must be set correctly to ensure maximum performance. Here's how to set the gap of a spark plug.

  1. Remove the spark plug wires. Use a socket wrench to remove the spark plugs from their chambers.
  2. Clean the spark plug if you are not replacing it with a new one. Remove all dirt and debris from the spark plug.
  3. Check the owner's manual for your car (or any appliance with spark plugs) to find out the recommended gap setting.
  4. Use a gap tool to check the gap of the spark plug. Slip the tool between the ground electrode and center electrode. The gap tool should fit snugly at the recommended gap width indicated on the tool.
  5. Push the tool between the electrodes a few times to ensure proper gap. If the gap is too wide, push the ground electrode firmly against a flat surface to narrow the gap and then check again with the gap tool.
  6. Repeat Step 5 as necessary until you reach the correct gap. Reseat the spark plug and reattach the spark plug wires
Good Luck
