These are really quite easy to do just time consuming. 1. remove the air ducting from the air box and throttle body 2. remove the accelerator cable and kickdown cable(if equiped with auto trans) from the throttle body 3. remove the 4 bolts from the throttle body and be careful to not ruin the gasket upon removal 4. remove the black cover from the rocker cover(valve cover) 5. remove the 2 coli packs and the spark plug wires. 6. remove the 4 spark plugs. Use NGK or Nippon Denso plugs and gapped at .032". Let me know if you need anything else.
the spark plugs are located in the head. you must remove the upper half intake manifold first, it has three bolts 12mm. then remove the black plastic cover down the center of the valve cover, six 10mm bolts. remove the two coils and plug wires. now you have access to your spark plugs. Good Luck
HAD THE SAME PROBLEM WITH MY DAUGHTERS CAR---CHANGED THE SPARK PLUGS AND OIL IN THE HOLES OF THE SPARK PLUGS WIRE TOPS--- CHANGED THE VALVE COVER GASKET AND ITS BEEN CLOSE TO 4 MONTHS AND NO OIL AT ALL IN HOLES---IF YOU LOOK AT THE GASKET YOU CAN TELL IT LET THE OIL OUT---THE GASKET SITS INSIDE THE VALVE COVER VERY SNUGLY--THE OLD ONE WAS VERY LOOSE---AS FAR AS OIL GOING INTO THE SPARK PLUG CYLINDER IT WILL BLOW WHITE SMOLE FOR ALITTLE WHILE BUT EVENTUALLY BURN OFF---HOPE THIS HELPS---DENNIS
you could have a bad injector or vacuum leak near #3. or you could have leaking head gasket. or you could have a burnt valve. testing will confirm what is actually wrong, it takes diagnostic equipment to illiminate what isnt the problem
