I just changed the Intake Manifold like three weeks ago. I changed all the PCV lines. But i put the rubber seals back into the intake manifold but i didnt put silicone.....i wonder if that is causing a vacuum leak....i seriously dont know what to do.... these are too many codes!!! I dont know where to start my car runs like **** at idle

i know what the codes are!!!! i just dont know what can be causing all of this......nevermind obviously this isnt going to help

Moscosoalfredo

andi have already tried a search and no one had all codes so....

With all the lean codes I'd say you have a vacum leak somewhere, or missed a vacum line. Double check everything you touched because you make it sound like these codes came up after you touched the intake and PCV lines. Also, any "hissing" sounds at all?

no hissing sounds i double checked all hoses .... i dont know what to do .... i am going to take it for a diagnostic

WOW!!! You have a vacuum leak somewhere...i noticed your sig you have long tubes on your car. you dont by chance have any exhaust leaks before the O2 sensors do you? if the O2 sensors are picking up on the fresh air being let into the exaust system by an exhaust leak that could cause it to think its running lean

If you reused the intake seals... the leak is exactly what you may have.[BTDT]
Have you done the simple spray test, around the manifold?
Damaged inj o'rings will also cause the leak[s]....

All of that makes sense to me....ok i will try that
