Well, today I finally got the car together(still waiting on BBB's, so I had to throw some stock butterflies on 
) and fired her up. Started right up, that made me happy. After going over our checks and making sure nothing is going wrong, the car started to warm up and idle.
Here is where the problem comes in... The idle was/is very rough, you can really feel it and see it in the dash. It *seems* to affect all cylinders. After about 2200 rpm, the motor is smooth as can be.
Now on to driveability... After starting the car, it will idle rough. when I start moving, the driving is somewhat normal(considering I now have a lightweight flywheel). If I get into it, it seems to have some power(harder to tell when you are the one driving and nothing to compare to you), but I am not sure if it has all its power. While driving, say 5th gear and I need to stop, I push in the clutch and the idle will drop and stumble a bit. It has even stalled a few times. If I were to brake from speed and let the idle slowly go down(keep it in gear), then it won't die, but still stumble. If I were to rev it up rather quickly and let off the gas, it will stumble for a few seconds trying to idle, may sometimes die as well.
What I did to the car(car ran perfect before mods).... In the last 3 weeks(motor mods), I have installed new rod bearings, stage 1 cams, valve stem seals, gasket matched heads, Eh runners, crankcase evacuation(PCV routed to exhuast, yes I plugged the TB), UDP's, 190lph fuel pump, silicon hoses, and some sensors and other stuff that I'm sure would not cause this.
My first thoughts were a vacuum leak, then maybe a ground or a sensor.... Then the thought of maybe the timing is off. Well, I have not had a chance to check the codes yet, but I will do that first thing tomorrow. I also have not had a chance to check vacuum lines and such(too busy having fun with the Quaife and new suspension!). About the timing... we double and triple checked the chains... I think those are good, but if it were the timing, I would say its the belt, here is why... We did not take off the lower timing belt cover to set the timing, we set the crank to TDC and the cams to TDC as well. Then we lined up the belt on the cams(not really needed this route). Next we rotated the motor twice, stopped at the first line and tightened the belt. Then we rotated 2 more times and then again. Every time the crank was at TDC, as was the cams. In theory, that would make the timing on and I believe it is... But this problem has me second guessing myself.
From the top of my head, thats what I have so far. Like I said above, I have not had a chance to poke my nose around and figure out the problem. The car was running great before mods... Also, I am running an LPM, but that has not been touched through the whole process.
Any help is a blessing! TIA!
EDIT: THE CCV IS CONNECTED AS NORMAL AND THE PCV IS RUNNING THROUGH THE EXHAUST... I WAS JUST NOTIFIED THAT MAY BE CAUSING A PROBLEM AS IT IS PULLING THE METERED AIR THROUGH AND RIGHT INTO THE EXHAUST. ANY THOUGHT?(not yelling, just trying to get attention at the botom )
Now on to today's pics!
