ok i have a 1991 honda crx hf with a what i believe to be a poorly done swap (bought it this way) when im driving at low rpms it cuts out and wants to die. If i keep it reved higher its fine. I bought a new throddle body position sensor but havent gotten it in yet i know its running rich and flooding out even in the morning sometimes it takes like 2 minutes of craking before it will start could it be the ecu or someting internal with the motor let me know what you think it would be a great help

 

Do you have a check engine light on? wat ecu are you runing?

 

the check engine light come on sometime when i egine brake or just let off in 5th and 4th gear and just let it slow down not sure on the ecu ill look where on the ecu will it tell me what it is

 

Yes it will say wat ecu it is on it. Do you kno wat code your throwing for the check engine light??

 

The ECU will have a sequence of characters that looks like this, "-Pxx-" The "xx" is what you need to tell us.

Also how do you know you're running rich? Do you have blue smoke coming out of the tail pipe? What about checking your plugs for black soot?

 

yes it blows a little smoke out of the exhaust and you can really smell it ill check the plugs two just not done with school till 4 so ill post back then

 

ok i got my throddle body position sensor and put it on and fixed my problem but i noticed that it has adjustable screw slots so is that to richen and lean it out if i move it around i set it in the middle and its working good not perfect still a tiny stutter at low low rpms so if you could tell me what that would do it would be great.

 

ok i looked at the ecu and when its running there is a red blinking light in the center of it and its not the facorty ecu because it does not fit in the 4 prongs hanging off off it
the ecu number is : 3782-pr4-a01
what one should i have

 

damn ur running an integra ecu for the b18 get one out of an 88-89 manual integra, they use the almost same motor as a zc (just different mount locations). it's a pg7 ecu

 

ok well that will work with my zc its a dohc not single and whats the blinking light mean?
