2002 Ford Mustang Piston Fire-Order?
I just need to know which piston is where so I can replace the spark plug on #2. I'd like proof so I don't end up replacing the wrong one
As you're looking at it, the 2nd cylinder on the LEFT. Those are the lower numbers. 123 or 1234. Replace them all. If you replace 1 why not just replace them all but when do do 1 at a time but you need to replace them all V6's 1-4-2-5-3-6 On those engines, firing order is important, but since they are coil-over-plug, it's pretty much impossible to get the firing order mixed up because the wiring harness is shaped and formed in such a manner that they're set to meet their designated cylinder without being so far off to where a technician gets confused. Only very rarely does this happen nowadays. Not like with distributors or distributorless ignition systems that use spark plug wires which can get mixed up if the technician isn't careful.

- Recommend best piston rings? What are the best piston rings out there? I've used Hastings twice and both engines end up with blow by. Ford 302.
- Should I receive money from ford for my vehicle randomly catching on fire? I had a 2009 ford ranger that we didn't have insurance for yet. About 80000 miles on it and the front end just catches on fire sitting in my driveway. Totaled the vehicle. Not having any insurance I'm screwed. Do I have a case ford should pay for it?
- 2002 Honda Civic or 2002 Ford Mustang as first car? I'm debating on getting a Civic with nearly 30 mpg or a Mustang with nearly 20 mpg, and I also live in Indiana where we get around a foot of snow every year.
- Ford 300 starts smoking from oil cap after 1 minute of runtime and radiator smells like a wet fire pit? It was running fine then it started acting hard to start off and smoking a little so I figured oil. Put some more in and it straightened up for a mile or so then started acting up worse. It began to have a knocking noise like an old diesel tractor. I don't understand what it is because it starts up just fine but won't run for more than a minute before it starts pudding and knocking. Also there are tiny pieces of rust chunks in the radiator and it smells like a wet fire pit.
