i just finished installed my new radiator and and my upper rpm intake.....i doubt its a problem with the radiator, so i know its with the intake....the car starts but doesnt idle. it starts but shuts right off. im guessing i forgot to plug something up....i checked around the Maf sensor, IAC, egr....nothing....everything seems plugged and fine.....i remember plugging everything behind the intake....but might of plugged it wrong?maybe.....could it be a vaccum problem? what do you guys think? what sensor or hose would cause this? thanks guys
