Hi, I;ve recently swap a B18C1 into my 94 CX. I am having some rough idling at start up, sometimes it even turns off.

I hope someone can solve this problem for me.


Spec:
B18C1 Stock w/ JG CAM GEARs (Timing has been done at shop)
p72 ODB1 ECU No chip
Sports Compact MSD 6300

 

have you tried cleaning your fuel system with a fuel additive?

 

Not yet, but would that cause the engine to idle rough all the time,

the only time the engine idles very rough is when the engine is cold and once the engine warms up alittle bit, it idles pretty good.

So, it must be someting else, or it could just need cleaning in the fuel system,

I'll try that, thanks


Any other Help???? Anyone????

 

It could be your idle control valve ir tps sensor that is not sensing a cold engine. When a engine is cold the ecu detects that and should idle a little high until it warms up. It sound slike yours is not doing it.

 

i got the same problem...it is the cooling temperture sensor......i have yet to fix mine

 

where is the cooling temp. sensor??
