i just swapped my mrev2, 5/16 spacer, polished plenum, and polished throttlebody for the oem setup. i did the install corectly and when i went to turn on my car my engine cranks but it wont turn over. does anyone have any idea whats wrong?????

 

Do you mean it spins over but wont crank? Did you reconnect the TB?

yeah i plugged both in. does the throttle body go "bad"? i bought it used.

 

Yes TB failure is pretty common, you can attempt an idle air relearn but most of the time miscalibration will cause rough idle, stalling but will allow it to start. Since its used i'd bet its a bad TB, swap the old one back and atleast try it.

and it just keeps cranking.

 

Also to test the TB before removing it you can, Remove the Intake, Turn the key to the ON position, put the car in 1st if MT and D if AT, and press the gas pedal and have a friend see if the blade moves.

i am alone...

 

the TB blade is moving when i go from the "on" to "off" positions.

 

Thats a good sign but you still need to check to see if its moving when the pedal is depressed. You best bet is going to be through back in the stocker and see if it runs.

old one doesnt work either. it does the same thing.
