also another problem i forgot to mention just dont want to make another thread

when im on the freeway the engine light goes on...and its only on the freeway..and it usuallys goes on when the car gets a lil bouncy witt the messed up freeways around here and cause the car is lowered...

any tips or info on this?

sounds like a dpfi throttle body and tps problem...look up the ecu for codes and go from there...!!!

 

how would i look for the code?

sorry im kinda a noob...
but thanks for helping out

 

pull back your passenger side carpet,turn the key to where all the cluster lights come on and count the flashing red lights in the ecu...!!!
