i thought the IAC was going bad so i swapped it out with another one..then i set the tps iac etc, still doing same shit cold start it'll turno on fine everything will look normal i'll go from Park to Drive and it'll shut off everythi,e.. only way it'll stay on is if i give it brake and some throttle like 5% throttle she'll stay on? it'll even sound like it has a huge cam and throttle will float meaning if i tap the gas it'll hover up to around 22-3000k rpm and just stay up there? need help could it be a bad ground or what do you think anyone been thru this mess? checked the grounds all look fine if i had a vac leak iac will go down to 00 and my bl would be very low and rich...
