1999 safari van 4.3 6 cyl. has a service code PO

P0301 is a DTC code that indicates a misfire to cylinder one. It could be a bad spark plug, spark plug wire, rotor and cap, a dirty fuel injector, or the worst a bad head gasket. Cylinder 1 is the first cylinder on the drivers side, towards the front. Start with the simple and check the spark plug wire and add fuel injector cleaner to the gas tank. Good luck and hope this helps you get you van running 100% soon. If that did not help, then your going to have to do a tune up by replacing the spark plugs, wires and rotor and cap. You can get all the parts you need at Auto Zone and they can give you the step by step to get the job done with common tools in under 2 hours of your time. Keep me posted, be glad to know you got your van running 100% again soon.

Need info on replacing spark plugs and wires on 1998 volvo s70 2.4 liter engine . Any special tools required? Does the cover need to be removed to access the plugs?

No special tools required. Yes you have to take off the black cover. There should be like 6 or 8 bolts on the cover. 27 torx. After you take the cover off, you will have the ignition coils on top of the spark plugs. They are bolted down with 10mm bolts. take out the 10mm bolts and pull the ignition coils out. There you will have your spark plugs open to take out. Use the OEM recomended plugs. if you get the opti spark or some othe different multi electrode you will tend to have miss fires. Good luck

Tune up, troubleshooting fuel pump

this should help you. projects are listed on the side.,2546601/initialAction,repairGuide/shopping/repairGuide.htm?pageId=0900c1528003c156

the fuel filter is inside the gas tank and should only be replaced if it malfunctions.

for the spark plugs you need a special spark plug socket, a rachet, and a extention. if your not sure you can get a good tune up at a shop for 89.99 and up
