RPM problem (need to rev to 3k before car starts moving)

Hey guys,

I've just recently noticed a change in the way my car drives. From a stand-still...I've noticed I have to give more gas than normal to get going. All of a sudden I have to push my pedal to 3000 RPM's before I begin my normal (slow) start at a light. Normally what should get me going is 1500-2000 IIRC.

I've also noticed that my gas mileage has dropped since this problem started.

Any ideas what would cause this? I havent made any engine mods at all or touched my car since buying it.

P.S. It's a 1995 V6 Mustang. Not that it should matter.

How many miles on the car?

What kind of transmission? (I think I know)

When did you last check and replace your transmission fluid?

Thanks for the reply kscoyote.

158,000 km on it...roughly 100k miles. It's a manual transmission.

I just bought this car 6 or 7 months ago...so I havent replaced it. I dont know when it was replaced.

How likely do you think its the transmission fluid? Could it be a gasket?

That could be it. This is my first standard car, so I dont know much about how clutches wear down.

I do know that my 'release' point is very close to me having my foot right off the clutch. I have been assuming that it would need to be replaced soon. I guess maybe now is the time :S

Is that how a car would react if the clutch was starting to go? If so, how long do I have before it totally craps on me?

This may sound dumb but in case u didnt notice b4 or that (i think u would have) but check the handbrake and make sure it isnt on or any thing.

i think the Brake light would be on in the dash

my friends 2000 GT was the same now we knew it was the clutch cause we burnt it out (Factory and it smells baaaad) but the car would start moving about 4K+ rpm and then would drop back down after it engaged. when engaged if u gunned the throttle it would slip (the clutch).

I would tend to say it is the clutch

I dont know if this makes a diff, but even when I'm already going and I need to speed up; I need to jump 2k-3k RPM before I start acelerating. Your clutch will do that if its starting to go?

It's probably the clutch, but you should change the fluid at that many miles.

I've talked with some of the guys from work and they think I can adjust the clutch by pushing down on it and side stepping off of it so it pops back up. I'm going to try this on my lunch break, but has anyone heard of this working?

Older Mustangs on the 80s had a self adjusting clutch, but I think there were problems with it, and the feature was removed.

I'll give it a try and see if it works. Is there any other easy way to adjust the clutch?

While we're on the topic, will it be a nightmare to replace a clutch on a 95 mustang? My dad's got the tools and we could do it...just worried about how long it takes. I dont want to waste a weekend fixing it if I dont have to.

P.S. Thank you kscoyote and 06BlkMustanGT for your quick replies and help

I received a quote from a local shop at $600-650 CAN. Still looking for quotes. I think its best to have a shop do it.

95 Mustangs use a cable for the clutch, correct? Not hydraulics? Can't I tighten the cable?

Shouldn't cost more than $350 US. At least around here -but COL is cheap here.

Swapping the clutch on a RWD vehicle is easy. Just check your u-joints, etc., while you have it apart.

Wow, $350 US...I'll ask around then.

I'm going to get a Hanes manual and check out how easy your easy is

Thanks for all your help kscoyote. If you ever come up to Canada, I'll buy you a big pitcher of quality beer
