Weird Noise when Accelerating
I have a 99 V-6 Ford Ranger and I just completed the 90K service. The problem that I am having is when I accelerate and press down on the pedal, a "clicking" noise occurs until I step off the pedal. It is more pronounced in 4th and 5th gears. If I slowly accelerate, the noise doesn't occur. It's hard to tell where the noise is coming from although it does seem to be coming from below the engine. It doesn't affect the performance, meaning I am able to accelerate, but I don't know if this noise is a concern? Thanks.

Sounds like the AC compressor to me, i do know they do this from time to time, i would imagine its normal. Have you tried to open the hood and have someone push on the gas? Maybe it'll still make the noise when its not in gear, then just listen for where its coming from and let us know.

If it only when you are "hard" into it, maybe a mount could be loose? Im thinking you would actually feel the motor "jerking" though. Like Dain said... it could be any number of things.

I don't feel the motor jerking......and it only makes this sound when I press the pedal....even semi-hard. It doesn't seem to be affecting the performance, so maybe I'll just try to ride it.

You're getting engine ping. Either a problem with the EGR or the MAF sensor needs to be cleaned. The more throttle you give it, the worse it should be as the timing curve advances. Prolonged driving with it will eventually pit the pistons.
To know for certain if its ping, put in 93 octane fuel plus a bottle of octane booster. If the sound goes away or lessons then its definitely ping (pre-detonation).

Thanks everyone for their input. I'll put a higher octane and see it the sound disappears. I'll let you guys know next time I feel up the gas tank.

I also have a 99' Ranger. It has 51k on it. I have had it for about two months. What you are describing sounds exactly like what I am experiencing. I noticed it the day after buying the truck and the dealership added checking it out to my purchase agreement. Now I just need time to take it over so they can see what I am talking about. When I get it in I will let you know what it ended up being.

Please let me know Chadwj...I would be very interested.
From what the webmaster stated, I called a local Ford dealership and told me that it could be a "pinging" problem. He told me that some Ford trucks with higher milage actually require higher octane fuel and that this is quite normal. I'll let everyone know in couple of weeks.......although it may take couple of tanks to see the difference.

I have news. I haven't made it to the dealership yet, but I did fill up with 89 octane gas instead of my usual 87. The pinging is gone. Does this mean I need to have my MAF sensor or throttlebody cleaned? If I have them cleaned could I go back to 87 octane again?

I believe TSB = Technical Service Bulletin, in other words recall from Ford. Here's a link for 99 2WD Ranger, 3.0 V6 FFL http://www.alldata.com/TSB/20/992022DI.html.
Does anyone know if there is a mileage/date that these fixes are good for? Thanks.
