2001 Ford Explorer Sport 2DR
4.0 V6 SOHC
94,010 miles
I've recently noticed that my acceleration has greatly changed within my vehicle. I pretty much have to floor-it to even get my vehicle moving at a decent speed. Once I'm going and driving the acceleration doesn't seem too bad but when at a stoplight or stopsign the acceleration is horrible from a complete stop. Any ideas what the issue may be?

Is the check engine light on? If so get the codes pulled. Something quick & easy you could try would be to clean the MAF sensor with some maf sensor cleaner to see if that makes a difference....

Well I followed up on this issue and brought it to the mechanic recently. Apparently they couldn't find anything wrong and recommended a tune-up (spark plugs, air filter, etc.) and also recommended using fuel injector cleaner. I don't see how a tune-up could fix an acceleration problem but they think it will. What are your opinions?

That would depend on whether your acceleration problem is actually a misfire or not.

>>I don't see how a tune-up could fix an acceleration problem<< Are you serious? When is the last time you had this tuned? Injection cleaning?

Exactly what i said. If your getting hesitation because one or more cylinders are misfiring, then that stuff might help. If your hesitation is fuel mixture caused, then that stuff won't do anything for you.

I have to agree that a long over due basic tune-up/servicing; could be the problem; as long as there are no other obvious issues found?
At times these kinds of repairs are a process of elimination; things that you’ve tested and know are not the root cause of an issue.
It’s called a strategy based diagnostic procedure; which is a set of predetermined test steps that you follow; things like.
Have they/you check for codes, is the computer in fuel control, is fuel pressure & volume within spec and or is there a restricted exhaust system (plugged converter)? If by chance this vehicle has traction control; is it possibly malfunctioning; requesting a power reduction from the engine management computer?
If all of these things, haven’t given anyone a lead as to what the cause is; then yes, tune it up, making sure that all the basics are covered.
No it’s not a guarantee that that will be the end of it; but at least you’ll know; it’s not a stressed out ignition system, plugged fuel filter or that the neighborhood chipmunks haven’t used your air cleaner box, as a storage bin for their winter cache. LOL

Thank you guys for the replies. As far as I know my vehicle has never received a tune-up and it's a little over 95k miles. The check engine light is not currently on and the mechanic didn't find anything noticeable wrong that would be affecting the vehicle's acceleration. Since money is an issue, I have been pretty much trying to avoid all vehicle costs as much as possible (aside from oil changes). Seeing how a tune-up is around $400 dollars, I am wondering whether its worth putting the money into the vehicle. Since there is a good amount of work also needed to be put into the vehicle (cosmetic, some mechanical, and other stuff), I am debating whether to put any more money into it. I would like to keep the vehicle but if the acceleration problem isn't solved with a tune-up then it basically wouldn't be worth putting anymore money into.

Your call.
Either put a few hundred into the vehicle or apply for mortgage to buy a replacement. They’re both going to be sitting in your driveway; costing you money. No matter how you look at it; owning a vehicle and maintaining it, is always going to be a financial burden.
There’s no right or wrong way to go here; buy a “new” vehicle and it comes with big payments. Buy a previous enjoyed vehicle; the payments are smaller but there will be maintenance & repair costs.
Fixing something that you already own; it’s just the repairs that need to be addressed. Before going ahead with the tune-up; have the entire vehicle checked for other obvious up coming repairs. Make up a list, setting priorities for safety, drivability, cosmetics and costs.
Once you have that you can make a more informed/educated GUESS of what’s the right thing for you to do?
