Do you need a tune after changing throttle body?
Anytime you change to a CAI, Throttle Body, Exhaust, etc. You always want it tuned for calibration. Only enhance it by throttle response, acceleration and sound of exhaust.
How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
How does the throttle body work on a car?
The throttle body is a tube that controls the levels of air that enter the engine at any given time. The throttle position sensor combined with the air flow sensor communicate with the computer of the car and tells the car how much fuel is required.
How to do throttle body re-Learn Chevy Malibu?
1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. 3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light.

Do you need a tune for a new throttle body?
If you’re just installing a throttle body spacer by itself, then a tune is not necessary. On the other hand if you’re installing this spacer along with a new throttle body or intake or any related parts then a tune is always recommended to receive the most possible gains from your modifications.

How does the throttle body work in a car?
A throttle body is a butterfly valve located between the air intake filter and the intake manifold. It regulates how much air can go into the engine, based on driver input through the gas pedal. As more air flows into the engine, it injects more fuel, thus allowing for more power.
