Hello: If the truck is not missing the what you are seeing at night is the effect of high voltage 50,000plus volts passing through the wires. Make sure the wires are in the proper looms and routed away from ground the best possible. Do the spark plugs have the proper gap and are they clean. Are they A C Delco plugs. For 1988 plugs only good for about 50K miles.
Instead of explaining it, Go to Youtube and type in how to change spark plugs. This will give you a view and pictures. When you purchase your new plugs be sure to have your auto info such as year , make , model , engine size. Plus ask them what is the GAP measurement. They do sell plugs that don't require gap. Plugs, Gap tool, anti-seize grease (small packet) $.99. Whatever you do, don't forget the grease, it keeps your plugs from being welded in the head and alot easier to remove. Good Luck
Make sure the parts guy sold you the right spark plugs for your car.
Make sure you got the right gap and make sure you put the plug wires back on securely and in the correct order. I usually do one plug at a time so I don't mess up the order.
You remove the rectangular plastic cover on top of the engine(2 screws), under that is the plug wires and spark plugs. Pull wires straight up, remove plugs with proper spark plug socket, extension and ratchet, reverse to install.
Platinum plugs are not required but will allow longer change intervals. Check the gap but do not gap them, if they are not properly gapped. Bring them back and asked for new ones.
The metal's on the Platium plugs are harder then copper plugs and can break upon trying or break in your cylinder when in uses.
Find out what your spark plug gap is, and the size of plugs you require from your owners manuel. Purchase a Spark plug socket for your rachett (also a rachett extension if you dont have one) And a set of Gap Measurers. Pull out the spark plug leads from the base making sure you don't pull on the cable (can damage the lead if you yank on the cable instead of the boot) and then screw out the old sparkplug and check for damage/wear. Set the gap on your new sparkplugs and screw them back in using a torque wrench for the final turn or if you don't have one only hand (do the final turn without using the rattchet just grab the wratchet extension and twist with your hand).
the spark plugs wires are directly located on top of the engine and the spark plugs are down inside the holes in the valve cover itself. I believe there are also 2 coils on top of the engine, which hide two of the spark plug wires which are attached directly to the underside of each coil, remove the coil pull it upward carefully and you will find the spark plugs for those two in the hole underneath the coil for each one. If you decide to replace the plugs, make sure to check the spark plug gap even if they tell you they are pre-gapped as pre-gapped spark plugs are usually gapped for more than one particular car and it may be incorrectly gapped for your specific vehicle. If you decide to also replace the spark plug wires, you will have to purchase the spark plug wires for the underside of each coil seperately because most local auto parts stores only sell 2 spark plug wires in the set that go onto the non-coil attached wires and plugs, and you have to purchase the coil spark plug wires seperately. So all in all you should have 4 spark plug wires, 2 that attach directly underneath the 2 coils, then 2 regular type wires that run to the other spark plugs. If you look at the valve cover and see the wires, you will see what i am saying better. Just don't forget to ask the autoparts store the spark plug gap recommended for you car, and adjust the gap on the plugs as needed. good luck.
