'03 V10 w/ some issues

I've got an '03 with some kind of problem Basically it runs rough and has sporadic pops and back fires. If it was your run of the mill non-computerized carb type system I'd say it had some timing issues. That's kind of what it acts like.

Admittedly I haven't dug into it, at all, because frankly I know squat all about the engine and it's likely issues. What I'm hoping for is some informed input given the most basic description I've just given. Or at least a direction.

If you can solve the problem without a major rebuild (I can dream!) I'll fund enough of your favorite beverage to be considered a "binge".

Possible misfire? When was the last time you changed your plugs?

Well, some definite misfire I think, but big question is why? Spark plugs are an unknown as this is a recent purchase. This is probably not a bad place to start, and is relatively cheap unless I have to get into COPS and such, but I'd rather avoid just blindly tossing too much money at it.

If the plugs are unknown, then I would go ahead and have them changed. It needs to be done if it's never been changed. How many miles does your X have? You should change the rubber boots, too.

You could start with checking for codes. There may be some even with the check engine light off. Where in Ohio?

As previously stated you will not be wasteing money changing plugs and plug boots. Some of the V-10 engines that has had the plugs changed has had only 8 plugs changed, of course the back ones are harder to change and some have never had then changed. Its really not that hard and new plugs and boots if you do it yourself is a little less than 100.00. Use anti-seize compound on the plugs and make sure you check the gap before installation.

Autozone or whoever will give you a basic checkout which will be sufficient in most cases to point you in the right direction. If it's a COP or even a plug, it will quite possibly tell you which cylinder from a code. This will not trigger the light. (seems lame, but that's what it does) You can swap a cop from another cylinder to see if the problem moves to test the cop. A bad COP is more likely than a plug for a steady miss IMO.

Figures, of the few weeks I am actually busy, the next 2 are it or I would be happy to give you a hand. About an hour+15 away.

It's not a critical project since it's not a DD or even a backup vehicle at the moment. Just something picked up that needs some fixing. It might just still be sitting right where it's at 2 wks from now. Hehe.

Well if it's still sitting in a couple weeks, PM me and we'll work something out. I'll probably forget if you leave it up to me. I have serious CRS!

No promises I can fix it (cheap), but we'll have fun trying anyhow.
