So i've had countless issues with my 01 v6 within the past year- cracked water pump, cracked oil pan, bad fuel injectors, fuel pump... But recently i threw in a 65mm BBK performance throttle body along with a cheap cold air intake. Every time i put it into drive though, it takes no less than 30 seconds to even register and even propel the car, while the throttle valve is completely open (In park and neutral it revs totally fine.) I've been been told by some it may need a tune, but by others that it doesn't and its just the throttle position sensor or MAF. I even went to a Ford dealer and was told a tune wouldn't help, but rather it was the TPS or MAF. Any thoughts?
