P0305-Cylinder 5 misfire detected
P0316-Misfire detected on startup (First 1000 revolution)

Any suggestions as far as parts that are malfuntioned to these trouble codes. Maybe someone can give an idea with their past experience resolving this issue mechanically. THANX!

How many miles on it? Have you tried a tune-up yet?

primerff · 04-18-2007, 06:36

Its got about 69,000 miles and so far I replaced the plugs on it. My only problem that I can think of is the coil caps and you know their not cheap. Maybe someone can relate to my problem, I'm open for suggestions,THANX!

more than likely a coil.

Replace #5 coil.

My problem was fixed when I replaced my coil to #5 cylinder.Your trouble code P0308 pertains to #8 cylinder so I would start to replace the coil to that cylinder. Next P0174 can be an O2 sensor in bank #1 that is malfunctioned. I have a website were you can buy O2 sensors that are OEM for a good price.

thanks...I'll try the coilpack. What is the website that you spoke of for the O2 sensors?

website for O2 sensors is Discount Oxygen Sensors - Bosch Oxygen Sensor - Free Shipping - O2 Sensor
