alright hoping someone can shed some light on my issue here.
I have a 2000 Mustang 3.8L Obviously. 5 Speed.
Recently replaced the clutch with OEM Specific by Vin Right from Ford (know a guy there and got it better price then any aftermarket ones) had it installed and it grabs nicely. I also had the Flywheel resurfaced. Now when i ease off the clutch abit to get the car rolling abit i get wicked vibrations through out the entire car. but when i let off more and start giving gas it smooths out completly. Anyone know what would be causing the vibrations?

Also while im posting I may as well ask what would cause my car to run like a bag of S**t one i get the temp up just from driving and when i stop and turn the vehicle off, run into a store or something and let the car sit for about 5 min or so. i go back turn it on it runs horribly for awhile runs very rough give it cause and its like its missing.. any idea on this as well. any help is greatly appreciated.

How long ago was the clutch installed? They will chatter some when they are new as you break it in and it seats itself with the flywheel. Could be the install, also the throw out bearings are known points of weakness on these cars, and if that's bad it could cause some chatter.

For your second issue I would check the thermostat, it may need replacing. Make sure you've got sufficient fluid levels as well.

Your car running roughly could be a bad MAF, coilpacks...but let me pinpoint something out!
You replaced the clutch, resurfaced the flywheel and lets think for a second the clutch has been installed correctly, what about the driveshaft? We could have an balance problem here...there could be a possibility that the mechanic havent marked the driveshaft position and now your driveshaft is out of balance, wich can of course cause other problems!
Lets get back to the misfiring situation.....you might try to check you fuel pump or injectors because maybe your interpretation of misfiring is a pinging that also could end
in an catastrophe.

Dont get crazy check your MAF,IAC,TPS and O2 sensors, fuelpump and fuelinjectors it is very hard to respond correctly without a vid or soundfile!
Hope it helped ya

Clutch was done about a month ago. i questioned the mechs about any break in time at all they said no it will be smooth right from the start.. but didnt sound right.. most things need breaking in. all bearings was replaced while we were in there as well.

didnt realize themostat would cause this big of an issue.. but ill have it replaced. all fluids are good check them regularly.

and for vsix
the mechanics that did it are very familar with this work. all do this on a regular bases so.. drive shaft and what not should be good they hopefully be lookin at it again soon. I've had all my ignition system replaced including coil pack about 3 months ago. i have not yet checked the MAf sensor. id assume once an O2 sensor was malfunctioning the check engine light would come on.. which it hasnt yet. so.. i dunno.. lol..

[vsix]

The check enginelight is not the bible!

My car ran one day like a corolla from 88 and my check engine light was quiet!

About the 02 sensnors they can cause the car running to lean so from my point of view

I would consider to get them checked.

I say driveshaft is out of balance so the last laugh is on you.

EDIT:

Between the almost continuosly aswering questions to my GF( she hates me sitting in front the laptop) and the running german TV and the neighbour that is prakticing
his piano...how about a break in time for your clutch? Juzz give it a lill time and see if it gets worser, cool?

[-cold-machine-]

ill have it rechecked again im open to all possibilities right now.

The vibrations are likely coming from the clutch. Possibly it's a bent disk.

The rough running sounds like a leaking injector, especially if it clears up after a while and only occurs after the car has been siting with the engine hot.

[-cold-machine-]

so should i try flushing out the injectors or just go replace them? the car is 10 years old and has over 160xxxkm on it and nothing been done ot this car before other then oil changes and battery replacement. and i got the car about 4 months ago roughly now..

[goren813]

Yeah there should be at least a gas tank break in period, I did 500miles on an aftermarket clutch. I would hope the shop would have the drive shaft back in the right way, this wasn't a DIY job so things like that we almost have to take for granted.

I took the rough running issue to get WORSE as it got warmed up and then restarted, not better, but the injectors could probably get cleaned up before you just replace them.

[-cold-machine-]

warming up it does worsen to a point. then restarting makes it alot worse then will smooth out from there back to what it was before the restart. kinda confusing really :S

Flywheel May Not Have Been Cut Properly!!

[-cold-machine-]

well had my injectors flushed ill give it a run tonight and see how running condition is now.. and give up date tomorrow.

[vsix]

Ya man do that and let us know :-)

[stephen]

You might try having the injectors cleaned and flow tested off the car. One place that does this is witchhunter performance (google them). If it's worse after the car sits with the engine hot it may be a leaking injector, though there are other possibilities.

As to the clutch problem. I am assuming the engine idles smooth and vibrates after the clutch pedal is pushed in. That suggests the flywheel and clutch disk are balanced right. Also if it's smooth driving down the road I doubt driveshaft balance is the problem. If I had to guess based on these symptoms, I would say something is wrong with the pressure plate or release bearing.

[-cold-machine-]

clutch problem is smooth with the clutch disengaged, once i start releasing the pedal and it starts makign contact with the fly wheel a lil is when i get alot of vibrations. No drop in RPM at all,if i was to ride the clutch a lil(i know,, big no no) but just the slightest bit of gas it smooths out. once the clutch is completly contacting the fly wheel its smooth again.

[stephen]

It sounds like something is wrong with the clutch disc or flywheel surface.

Take it back to the place that did the clutch and have them fix it.

[-cold-machine-]

I'll have to get them to, but got the car in getting a smallrust spot taken care of before it gets worse right now.

As for the update on the fuel injector cleaning.. Nadda. It DOES run smooth the entire time even after it warms up. BUT when i turn it off and turn it back on thats when its running rough.

[vsix]

Stay focused on the fuel delivery system...let your fuelpump checked!

Did you asked about checking your MAF, IAC, TPS, O2s like Ive told you?

Do that!

[-cold-machine-]

I'll hopefully be getting my car back over to Service soon. Still in the shop getting some cancer taken care of on the quarter panel before it gets any worse. I do work in a bodyshop/Service Department. Just they refuse to walk around to each others department to check on a vehicle. so..

Once the Rust is taken care of it wil lbe back over in Service being looked at again.

im definitely going to agree with blue here... if it wasnt chattering/vibrating badly like that with the old clutch and is doing it now with the new one it especially after having the flywheel resurfaced id be looking at the flywheel for the problem.. especially if its only happening while your engaging or disengaging the clutch... they most likely didnt resurface the flywheel properly there.. wouldnt believe how many times ive stood there and watched some of them mechanics resurface brake discs and dont even get the disc's on the machine properly... forming high and low spots on them..
