Well here is the deal. Can't boost but I know that is a boost leak in my ic pipes, every time I stop or let the revs down if I take it out of gear the idle goes to ~200 and up to 1500 and revs weird like that for a few seconds. The car gets really hot, I know they get hot but it gets alot hotter alot faster than before(doesnt over heat at all but the egt seems pretty high.) My car is really loud, kind of sounds like a tractor, but I think that is because of exhaust leaks and maybe a little to do with the fact there is no cat. Oh and the two biggest things are 1. the rad hoses get really hard really fast as if there is a blown head gasket and the coolant is getting compression in it, but my teacher said that he wouldnt be to worried about it and there hasnt been any other symptoms of a head gasket failure and I hope not since I just put it on. and 2. I noticed there is a growing wet spot(looks like oil) on the acc side of the motor by the ps pump from around the head half way down to the block. There isnt anything leaking on the ground but its annoying none the less. Any help is awsome and sorry for the unoganization of everything.

Help with what? You know the tests for a bad headgasket, and we can't tell you where a oil leak is from, we can't see the car.

The rev issues sounds more like a vented BOV than anything. That's definitely not a boostleak issue. Is that plumbed back in?

yeah its recirculated, I'll make sure the tube is on all the way though. I guess my two biggest concirns are could my car be so hot because it running a little lean and my compression seems a little low to me, its 135 across the board. Its even so thats not bad, it just seems low.

well I checked everything and made sure the recirc tube was sealed, drove it around and vola, no more funny idle. But stupid me, some chick pulled up next to me in a riced out civic and she revs at me and I wasnt going to have any of that so I go to rev back and play her a little sweet bov music and it was almost like a studder box, it was about that time I relized I forgot to plug in the mas. So I pull over and plug it in and it revs clean again but still has the crazy idle

Well with the mas unplugged it was measuring any airflow, i bet you have a fairly large boost leak somewhere or that your mas is bad. 135 seems really low. did you rebuild the bottom end or just the top?

Just the top end. It seems low to me to but it doesnt really bother me since its consistant through the whole motor

Thats true. Another thing to check is the base timing. Mine was off on my gsx and it ran like shit. Another thing is do you have any DTC's? Cause i had egr solenoid failure and it made my car run shitty, crappy idle and bogging. I really think it is something simple, you've done a boost leak test right?

yeah I did a boost leak test, but there was a leak on the #4 injector seal that I never fixed because I was in a hurry to get my car done. I dont have an egr so I think that is out. Base timing is good. Maybe all this is caused by that injector seal, I noticed that I'm running rich, between smelling gas and there being a carbon deposite on my rear bumper. As soon as I get around to putting my 550s back in I'll fix all the leaks or at least try, I tried to fix the injector many times but it still leaked. Any suggestions on how to seal it?
EDIT: as far as dtcs go I have a p0141 which I believe is my down stream o2 sensor(no cat) a p0172 or somthing, fuel trim bank 1(no idea what that means) and a p1140 or something, and that is my map sensor that keeps coming unplugged.

Well when you have a dtc that is engine related the car goes into safe mode, basically it runs rich as hell and is only meant to get you home or to a repair shop. You need dsmlink to get rid of some of those dtc's.

well the o2 sensor code is an easy fix and so it the map sensor, its the fuel trim that confuses me.

Yeah that's a weird one, is that the exact code? Do you know of any fuel problems like fuel cut or anything like that? Do you have any way to log? I bet that's why you're running rich.

I have a logger but my fuel system is all stock. so unless its the injector seal leak or the map sensor I dont know whats going on.
The exact codes are p0170(fuel trim bank 1) , p0141(O2 sensor heater circit), p0110(intake air temp circuit), p0100(volume air flow meter malfunction), p0105(map sensor circuit) I didnt relize I hade that many.

The intake air temp and the volume air flow may be from before when you had the mas unplugged clear the ecu and see if those come back (make sure the mas is plugged in :P)

well the rest of the codes are reappearing, meaning that I usually check my codes once a day and this is the first time there was a mas cose and an intake temp code.
