Just did an ls swap into my 91 civic hb and it works fine but out of nowhere i get a rev limiter at around 3200 and it smells really rich. If you gun the gas quickly it boggs really bad. I reset the ecu and then it works for a little bit but i'm not sure if it's the ecu, dizzy, a sensor, not sure,
It is throwing a code 4 and a code 9.
Please any ideas would be great.

Limp mode search and find out what code 4 and 9 is if i can recall thats somthing distributor related.

yeah i checked those sensosors and i'm having trouble tryiong to figure out why a tps or a crank position sensor would do this so intermitently

 

Crank and TDC sensors are fubarred throwing you in limp mode.

Assuming your car is stock, just replace the dizzy. If it's been wired to something else, check the wiring.

 

i changed the dizzy it ran fine but out off now were it did it again.so i turned off the car and good as new.maybe the wires my friend switched on the dizzy are wrong

 

i think we fixed it the crank sensor was diconected.so no more code 4 and 9.and no more cel

 

disconnected??...that'll do it

 

when it runs rich, you cant smell it, what you are smelling is unburned fuel, it could be from running rich, but you cant smell CO LOL
