i havew a 2000 cougar with a 2.5 v6.I just bought the car and the guy told me he thinks the fuel filter is clogged up because the car has a lack of power and will barely rev past 5 or 6 rpms.motor sounds good no knocks or pings no smoke or leaks.cel is on I was going to go get it tested but i wanna see what you guys thought first maybe somone else has had this problem/../??>.

 

Perhaps the rev limiter is doing its job @ 6000.

Lack of power =smallass motor.

 

+1

 

its not like that it creeps so slow to 4 5 6 or whatever.my boy has the same motor and his shit hauls ass i just wanted to know what was up with this thing

 

check the mass air meter my mustang would do that when my mass air took a crap

 

i will thanks man

 

also is the check engine light on if so take it to autozone and have them read it for you

 

If you just got the car and previos owner says it maybe the filter tells me they didnt keep up with the maintainence. I'd start with a basic tune-up, oil, filter, plugs, fuel filter so YOU know those are done and are eliminated from the problems. HTH
If there no check engine light Fuel filter is a good possibilty. If there is a light have codes checked as ^^^^ stated

 

also check the o2 sensor. mine went bad in the focus and had somewhat the same symptoms.

 

thanks guys.ill try all these things but i might have found the problem.
1.Inoticed that the tach seems a bit slow from what the motor is really pushing.
2. the car breaks up more and more the higher the rpms get.
3.Somtimes the car will die and wont start up. but if you check for spark
it fires right up.

I think it might be the coil pack i will have the scanner to find out for sure sunday
