Typically modern cars replace there spark plugs around 100,000 miles. As the plugs age (more miles) the gap on the plugs tends to widen. When the gap gets too wide , you walk outside to start your car and it just turns over but refuses to fire up. Some times,if spark plugs are left in the engine for too many miles, they become glued into the head by carbon and corrosion. Worst case scenario , you can not remove them and when you do they damage the threads in the motor head that holds them in. I think if you read your owners manual you will find that you are way over due for replacement. Buy the correct plugs and install them or have them installed and be sure to use Anti-Seize on the threads in case you ever have to do it again.

How Miles Should the oil be Changed? I been Hearing 3000 to 7 500 miles. Thanks for your Help


various manufacturers give various recommendations, anything upto 12 - 15,000 miles but a change every 5-6,000 miles will greatly contribute to engine longevity and smooth running. Less than this interval is unnecessary, there should not be sufficient deterioration of oil to warrant changing it. This is in reference to an average engine in everyday conditions.
I have a 2.2 Honda with 185000 miles on the odometer and it has had regular oil and filter changes around 6000 miles and it pulls very well still.
High performance engines , such as found in super cars or hyper cars might need oil changes far sooner becayse of the pounding it takes but unless you drive a Maserati, Lamborghini, Ferrari etc, you should be fine with the 6000 mile intervalc

Check engine light on engine acts as if missing new plugs wires and #5 spark pack missing again 6cyl 4x4 3.4 185000 miles


was it running this way before you changed the plugs? just a shot in the dark here possibly a defective spark plug, rare but not impossible. if it was running fine before changing them. Other wise I would take it to autozone and pull codes if it is P0350 #5 misfire we would use the process fuel, fire and compression. is there any engine coolant around any cylinders? Have you checked the coil packs? could be a bad coil pack. if no evidence of fluid around them proceeded to check for spark, fuel then compression. post back results or new post with more deductions. iis it no spark no fuel or bad compression.

I was looking to start working on my engine it has 185000 miles on it i havent had any problems since i bought the car but i dont want to either so where do i begin


Start by getting a Haynes repair manual on the vehicle and then follow the recommended services for each mileage until you get to the mileage you have. The manual will tell you what needs to be checked and how to check it and or replace it if needed.
