P1518.losing my mind!!!!!
Please help before i get committed to the mental institution!!!!
Back story..bought the car in january,ran great. New tac,pcm ,bcm in september 2012.
Intalled tr224 cam,ls6 intake,vararam,lt headers,x pipe.
Dyno tune w efi live.
Car sits for 2 months
pull car out get codes p1516,p1517,p1518 and reduced engine power after driving for 20 minutes consistantly in warm weather. Happens every time the car gets driven except when its cold outside(50 or less).then it will run with no issues.
Things i have done..
Cleaned grounds,replaced ground cables,
new ignition switch
changed throttlebody with known working one
checked door modules and harnesses
did the star connector removal of top to disable modules
changed ignition relay
checked all harnesses related to tac
took tac apart-looks good
brought to reputable shop-10 hrs labour - found nothing
took tune out-re tune.
Long story short,if its hot outside car will not idle right or stall,drive sluggish and go into rep.
If its cool,car runs exactly how it should.
Please help...im out of ideas and am sick of throwing money at this problem.
Thank you for reading this long post.
