i swapped a ls into my 98 civic and everything is fine checked the codes and the ones that popped up had nothing to do with it just evap but when i rev the car or drive it it cuts out around 2500 or 3000 rpm not sure dont have a tach but its around there

has this happened to you before or do you know what it is thanks

 

is it only 2-3k? or after 2k up it does it?

Maybe a Simple Tune Up Is Needed. Double check all sensors. maybe the TPS Throttle Position sensor needs to be adjusted or replaced.

 

im not sure i dont have a tach it gets up to like 3 it sounds like then it sound like a rev limiter and if the tps was bad wouldnt it throw a code

 

if it just needs to be adjusted no it wont. and now you say its like a rev limited i know what your talking about. my brother had this same problem and we took the distributor apart and seen metal shaving inside it so we replaced it and it was fixed. its either that or your ecu is in safe mode. which i believe means it found somthing wrong and wont let it rev high. but since u dont have a CEL then id check the dizzy.

 

alright i'll check that i just bought a brand new dizzy so its probably not that i guess ill check the tps

 

u might have got a defective dizzy.

 

alright ill check that stuff thanks for your help

 

i was just lookin some stuff up on it and the crank sensor will put it in limp mode so im goin to try doing the bypass

 

yea, thats what its called limp mode which it is in now.

 

A bad ECU will also put it in limp mode. If possible, swap ECUs and see if it fixes it.
