ok so i bought a 96 ek hatch with a gsr swap when i first got it i noticed it had the wrong ecu in it (p75) i switched that out with a p72 i drove the car and when i would floor it, it would break up and not go anywhere but if i ease into the gas it will go. the car also will not hit vtec. the previous owner wired a rsx gage cluster in it the rpms are the only thing working. i check my plugs and they are fouled out...i changed my plugs took it for a ride and it fouls out...i changed the map sensor i checked the wires and i noticed it had a ls distributor i dont know if that matters but i changed the cap and rotor anyway now the car will not start!

any help please let me know

 

I had the same issue with my gsr in my 91 civic. It sounds wierd but i had two vaccum lines wrong. I reran them and it instantly stopped fouling my plugs. I just googled obd1 gsr vaccum hose diagram. As far as the distributor goes, get one for a gsr. As far as i know u need a vtec dist. For a vtec motor. Hope this all helps

 

ok ill check the vaccum lines in the morning and let you know thanks!

 

alright so i got a conversion harness for the new obd1 distributor put it on adjusted the timing on the dizzy checked my engine timing the plugs arent really fouling out anymor but I cant punch the car or it will just studder and break up if i ease into it the car will go but anything punching over half throttle the car will break up any suggestions?

 

Is your check engine light on?
If it is, check your codes & resolve them.

 

check your code

 

Check all your basics first, a lot of the time is something simple.
If you have any codes resolve that first.

 

Ls distributor works, just all the bolt holes won't line up.

 

so i bought a new dizzy no vaccum leaks i had a cracked manifold put a new manifold but i still cant press the throttle more then half way with out the car like choking or missing any suggestions?

 

check codes. this has been stated a million times.

 

Check the fuel injectors. One might be bad.I had the same problem with my gsr swap and I found that one injector was cracked.

 

Check the fuel injectors. One might be cracked making function improperly.
