Ok guys i need help bad !,

My Car :5.0 Ford Mustang , King Cobra Clutch,Lowering Springs, Smog Pump Delete, Flowmaster Exhaust - No Cats - H PIPE, BBK CAI - Upper Pully

Problem #1: Car is idling ruff , Im guessing it has something ignition? or maybe my vaccum lines if so is it hard to replace vaccum lines my self and what is the procedure!

Problem #2: Car Shaking Aggresivley at HIGH RPM'S , And i feel like it lost power. The gear shifter shakes alot too but the whole car shakes. Now i just had the Clutch installed the guy ofcourse had to remove my Exhaust my DriveSHAFT And Tranny, Some ppl say the car is shaking from the drive shaft Monday im taking it to Mechanic to find out? Does this sound accurate?

So, your saying before the clutch swap it didnt shake and now it does? If thats the case, the driveshaft would be the first thing id look at....

+1 expecailly since u say lots of shaking at high RPMs... mayb something down there is miss aligned.... that would make since and be an ez fix... unless its already tough other stuff up... also what is you vacuum at idle??? that would tell u if u had a vacuum leak... u dont ahve nething that should really change it so it should be pretty close to stock... the fox guys will have to tell you what that is im unaware... ill look around tho

and about the drive shaft... and long as its push all the way into the tranny then the 4 bolts on the rear end are nice and snug that should be your problem.. unless the shop **** it up for you then it would could be a problem... depends on how much you trust you shop... do they do good work??

Do those steps and see if it fixes your idle. Easy to do so it would be an easy elimination or fix.

Drive shafts are balanced, it is possible the weight got knocked off

check the vaccum hose under your intake. it is a fat black hose not your normall sized vaccum hose. it tends to come off or crack b/c of the heat.
