Stupid car...now giving my attitude.. MIL light came on..I used my NEW MAC scan tool and got the codes
P0455-P1136-P1138-P1565---yes I checks all the vacuum lines..no leaks...fuel cap on tight...gosh my heads gonna PoP...help please...(AVANT) I know you must have some hints.???

 

P0455 is the most common for the other codes ( large air leak detected ) and most common culprit is the air pipe going into the inlet manifold from the EVAP canisterpurge valve

excess air would cause a lean fuel/air mix hence the other codes

 

Wat do you mean by excess air???...Soo I should check the Evap Canister then...if itz not working...am I suppose to change the whole damn thing???

 

nop just check all the hoses are good and no cracks, change the EVAP canister purge valve as a last resort but I gave the data to check that out so do it

 

Thanks..i"m at work now..gonna try it tonight..

 

Okay..i was able to try it like 5 mins ago...the Oms show between 26-27..soo i'm assuming that is normal operation...soo what now???....I don't exactly see a leak in the hoses..becuz one hose goes close to the throttle body which is hidden....then the other one goes near the fender...another trick to check for leaks...

 

not an easy one unless you know the engine like I do, I recommend the underside of the inlet manifold ( air intake side )

 

Soo your referring to the one going towards the throttle body???
