TURBO+GSR+CRX=?

i have a 95 honda civic with an ls swap and the car turns on right away and stays on. but i cant rev it or it will try to turn off ..what is there to check for there is an engine light on..i am using the cars stock ecu .
the idle stays at like 600 and wont go past 1500 rpm when it hits 1500 rpm its start jumping up and down

SOHC_4dr

i would start by checking the ignition timing and tps

TURBO+GSR+CRX=?

how can i check the ignition timing please

RagnarX

Check what code its throwing and go from there.

any other options or someone familiar with this problem

SOHC_4dr

yes for the light first. get a timing light and hook it to the first plug wire and point it at the crank pully. you'll see it flash and you'll notice there are marks (either on the t-belt cover or pully, dont remember) and this will tell you what degrees its firing at. to adjust it loosen the dizzy bolts and turn it to the IM to advance and exhaust to retard.

check that light

arrocha87

he said hes using the stock ecu foem his EG... wouldnt that make it go in limp mode or whatever with the LS motor?

RagnarX

Probably. How did I miss that? >.<, Get the right ECU, If the problem persists, come back with more info if its throwing a code.

SOHC_4dr

limp mode wouldnt cause it to die. i believe limp mode is OBD 2 territory, he is 1.

TURBO+GSR+CRX=?

should i try using a p72 either way i already threw the dizzy forward toward the firewall.and doesnt do nothing its really weird.

arrocha87

i dont know if its the right word or not i just know that having the wrong ECU specially one that is giving the LS way off the correct air/fuel ratio etc is whats most likely causing it to stall when he trys to rev it. feel free to correct me if im wrong.

SOHC_4dr

i know what your saying and that makes sense. it should still rev up, but OP you need to put in the LS ecu

TURBO+GSR+CRX=?

which one is the ls ecu

TURBO+GSR+CRX=?

also you think any of this has to do with timing

SOHC_4dr

i suggested the ignition timing in my first post so yes i do lol what year is the LS engine?

TURBO+GSR+CRX=?

its a 94 how can i check the ignition timing

SOHC_4dr

the ecu you need is P74, read the 6th post

TURBO+GSR+CRX=?

ok thanks but any other ideas

SOHC_4dr

not from me. not sure what else to tell ya lol sorry man.

PMK

I dunno if you already read or heard from someone but you should check your distriburator.

I had a friend with a 92-95 Civic coupe with the same problem, he got a new distriburator and it fix the problem.

Best luck to ya!

TURBO+GSR+CRX=?

doubt it can be the dizzy but will try thanks
so things to check for is the ecu and ignition timing thats it right

SOHC_4dr

i would have to say so

TURBO+GSR+CRX=?

ok well also this motor had a blown head gasket
will a p72 work

SOHC_4dr

prolly better than what you have now but it still wont be correct. just get the stock LS ecu
