first problem is that i installed a new clutch last week and a couple days later it feels like the clutch is not engaging how it should i am getting a loss of power when i go above 2500 rpm's and that is with any gears but gets worse with gears 4-5 any ideas other then bleeding the slave cylinder?? i am going to do that now

and my second problem is that i use to get an average MPG of 28-30 (300 plus per tank) and now i am getting 22 MPG consistently (about 240 per tank) has new plugs, wires, air filter and some BG fuel system cleaner and i dont recall it creeping up on me it was like one week it was good and the next it wasn't over this last week when i go to start up the car it has to turn over about 5 times before it wants to run and then the motor will run fine no codes or nothing the hard start will only happen on cold start up only when i go out to the store and only let it sit for about 30 min i will start it up and it will turn over the first time every time one a warm start up any ideas my friends???

car has 130K on it trans flush every 30 oil every 3 plugs at 60 air filter at 40 i kept up as much as i could on maintenance i dont beat the car up and its not a race car

 

I have heard that on some cars you can put the disc on backwards. (I have an auto Trans). I would also check your clutch master cylinder to make sure it's bled out and working properly.
