hey guys I can figure out many things, i really think a piece of my cat is clogging my xpipe in my exhaust. but incase there is other things that it might be here it goes

my car has been progressively running worse and worse since i heard a rattling under my car. (sounded like the firmiliar broken cat because i hit a curb or something) then after about 3 days the rattling stopped and this problem started happening

so i think the rattling part is clogging the exhaust.

symptoms:

6 out of 10 mornings or start intervals no idle unless I give it just a little bit of gas.

runs like poop unless i give it lots of gas.

will run normal but i definately need to give it 3 times the gas for same results.

if i let go of the gas 6 out of 10 days it will stall. if instead i give it just the slightest gas it stays running


please help.

I'm here for any LS1 swap type questions but i need some help with my 1U

 

attempting to comprehend what I just read leads me to believe it was well into miller time when you typed this out

 

no im just thinking in spirts

i am trying to diaq without removing the exhaust

some days it starts and idles and other i need to press on the gas just a wee bit

it always runs more slugish than normal

if i come to a stop light it dies, some times

 

Inspect/clean idle air control valve

pull the ecu out and open it. Look at the capacitors and see if there is corrosion where they are fixed to the board.

drink better beer than miller

 

No check engine light? Haven't checked for codes?

 

Cel must be first than go from there.

 

My name is sean Miller, I drink dos ekkes (XX)

I hope the ecu that that guy traded me isn't bad it worked perfect for a month, wher is the iac on this is it right in front of the intake?

 

I'm defiantly going to check the exhaust, the once jingley sound than now sounds like an exhaust leak but there in no leak, it's coming from inside the exhaust.

But I like the idea of looking at the iac
