ok... just finished swapping a 97 LS motor into a 96 dx hatchback. motor is acting up. when im driving im just babying it, but when 2nd 3rd and 4th comes it starts bogging sometimes. it just stops like im not even giving it any throttle whatsoever. HELP ME PLEASE! any imput?

 

no one?

 

is it throwing engine code?? what mods you have on it?

 

Any codes? Sounds to me like you may have a bad MAP sensor, or the TPS/MAP plugs backwards.

MAP or TPS usually causes a big bog because your ECU doesn't have a clue on manifold pressure.

hth

 

excuse my noobness on these subjects but where are those sensors located? and yes the engine is throwing a code, but wouldnt the engine be doing that all the time? this only happens sometimes, when im driving normal.
