ok now what
ok now what Ok got all this done in my sig,
And now my oil pressure varies on idle sometimes its around 20-30, it use to be around 40 or higher before mods.
When im driving and I come to a stop, I press the clutch in, the oil pressure drops really low and its like my car wants to stall out, the oil pressure also drops below 20 sometimes during this. I wish i could give a more detailed description but thats what happens. What the hell, brand new ported oil pump and now what, my mech put 20w50 in my car for some reason, could this be a problem he said it had an oil leak after they installed the new oil pump, I was wondering if with the thicker oil it would just hide the leak temporarily, but I dont know. He also told me that with this high performance vehicle it needs some thicker oil to run better, I brought him some 10w30 to put in after the install and for the break in, they put all the oil drained few days later and replaced it with 20w50.
Any ideas on any of this: What could it be "low oil pressure"? Why the thicker oil? Was it to cover the leak temp or is this what the car needs now, cause i was running 5w30 before?? Also whats the normal oil pressure where should i be at??

Could be many different things.20w50 is actually raising the oil pressure.If you had 5w30 in it now the oil pressure would probly be 10psi at idle.
Now something it could be.
Cam clearance,knicked Cam bearing during install
faulty ported oil pump
oil pump O-ring cut or not seated right
oil pump pickup tube clogged
lifter preload
motor bearings hurt from low oil pressure the first time.
Could be many things as you see.I'd be kind of sketchy on driving it if the pressure is dropping too much. Should be 40-45psi while cruising at 2krpm and 60+psi at 6000rpm.

When im cruising its up around 50 and fine its just during idle and stoping it drops real low im not sure what it could be. I was thinking maybe its not low oil pressure and if maybe my clutch is goin bad that when engaged its not fully engaged and trying to make my car stall out, cause when I do come to a stop my lights flicker and guages go wacky.

50psi is fine when cruising but I would check it with 10/40 oil to make sure the 20/50 isn't hiding something.

That is what im thinking the 20/50 is hiding something, would a thicker oil possibly hide failing oil pump???? or other problems such as kinked o-ring??

Check your plugs, mine did the same when I first installed my headers. I didnt have the plugs in tight enough and the plug wires werent on tight enough either and every once in a while when I was at a light the idle would dip to 500 or so rpms. After doing thsi twice in a span of a day I checked my plugs and two were lose and so were a couple of the plug wires so id check those too. You dont need to give the plugs the grip of death but make sure they are in tight enougha dn the wires are all on tight.
Well when my oil pressure was good my idle was at 800-900, now with the low oil pressure its down to about 500-600 I dont know how it happened I didnt touch the tune, however when the tuner reprogrammed the computer to pass inspection I wonder if something got screwed up? I wonder if my throttle body is screwing everything up the thing sux gets stuck at different rpms. What could cause the low idle then if I didnt touch anything???

The tune was changed to help pass inspection and now your idle is too low? Sounds like a tuning issue to me if that's the case.
If the tune isn't the issue then maybe a TPS (throttle position sensor). Let Kevin weigh in here. He is obviously the most familiar with the car.

He barely comes in here. And I dont really know how to get ahold of him. Except e-mail but I forgot his email 
. All I know is that it wasnt like this before it was made to pass inspection and I watched him do it all he did was go into a program and change everything to no error reported so I wouldnt think it would be with-in the tune. Im leaning more toward the throttle body this bbk sux like I allready stated or could just be a sensor. I guess I could change out to my stocker and see if everything works, but they said they adjusted the throttle cable to make it work with the bbk any idea how to put it back to fit with the stock tb??? AHHH what a mess I got myself into with this new h/c set-up.
