it was working before..I decided to turn my car on and mess with the idle some more..

now my motor wont let me pass 4000rpms...it bogs like as if my rev. limiter is set at 4000rpms....wierd...wasnt like that 2 days ago when I was messing with the idle..i changed ECU's that didnt work...

 

That's limp mode and you should be throwing a solid cel. Is it a chipped ecu?

 

Try letting the ecu unplugged for a wile, check make sure all your plug wires are pushed in the whole way.
Codes?
Does the car run smooth when below 4k?

 

When my dizzy went out in my B16 EF it wouldnt let me rev it over 4K. Check the codes and see if maybe it is throwing a distributor code.

 

my dizzy is brand new....the ecu is a chipped ecu...but it was all working 2days ago...untill I turned it on..I will double check my ecu codes though...

 

If the chip is loose it will put you in limp mode. Something is up with your chip.

TRY CHECKING CODE FOR TDC IN DISTRIBUTOR AND TRY CHANGING THE CHIP MIGHT HAVE WENT BAD.

 

well I have a fried chip..that is why I have this problem..
