Thanks for the site its great I have two problems my 2006 ford ranger v6 3.0 wont rev up over 2500 rpms in park I tried this because it wont go over 80 on the road could there be a restriction on it and could I remove it also my alternator seems to click on and off every minute or so it spins when its just sitting and running.
Do you

Hi, on alternator, how do you know it's 'clicking' on and off? Are you sure it's alternator?

On the rev problem I suspect fuel flow/pressure. Maybe clogged filter?

Not sure its the alternator I just assumed it was when its running in the drive I can watch it click on and start to spin then it shuts off while the belt spins around it what else could it be also with the idle when I get to 2500 rpm in park it shakes the engine are you saying its just the air filter sorry im just beggining to work on cars new to this thanks for your time though

Now i'm wondering if your alternator belt is tight enough or it's worn or both.

People who dont have to pass emissions usually remove converter or gut it out. It's worth some money for scrap. 1 test is to unhook exhaust in front of converter and see if vehicle runs better. Usually when they go bad they smell funny(rotten eggs).

I have three converters one main one then a y shaped one that seems usless the main one is brand new the y one is stock I do have an emmisions code on I guess my main question is is it ok to drive with it like this will it hurt the truck it runs and drives great but it just scares me that I cant go over eighty and when it just idles in park there is no stalling but the rpm are as low as possible and also would carb cleaner help or a new air filter

Do we know what it is? And you mean you have pre-cats as they are called. People gut those 2. You might look at throttle plate for dirty/greasy and clean it. Have you ever cleaned changed the IAC valve ford has a slightly diff name for it. ICV maybe.
