Guys as mentioned above, having those problems, which is giving me bad mileage in addition.

its a civic EH aka EG, whose engine was swapped by the prevoius owner, no details of swap ! I found out that its a SO4 from ZC series, Jdm i believe. 1.6 SOHC, manual.

it was not smoking when i got it afew months ago. I had the timing belt changed, also drained the radiator liquid which was plain water and filled with Honda all season coolant type two. I dnt know exactly how long after this it started to smoke, the idling as well.

in solving the idling issue, i had the throttle body cleaned ( the mech just sprayed sm substance ) . But the idling issue was still there. From this point on i realised that the engine was smoking.

From the time i bought the car, the CEL was flashing, so decided to check on the error code, which ended in me changing the distributor, upon which the CEL disappeared. ( the distributor was a recon set, it gave me shit and engine died on the road ! Changed another two and its running now)

Hence the issue of smoke and idling persisted, reading forums guided me to change the coolant temp valve and a clean up of the idling control valve. On the first start it seemed that idling had disappeared, but it s still there, but not as bsd as before. The smoke however is still the same or even worse.

I dnt know if the issue persists because the coolant temp valve being not a genuine part, is not doing its job or what. Also the cleaning of the idle control valve was done while the coolant tubes were still attached.

i am thinking of the valve which is on the exhaust manifold, if thAt could be the culprit. The mechanic seems to suggest that it could be the ECU, which needs to be checked.

i am. beginning to wonder if it was the coolant which i emptied into the radiator is csusing the smoke ( four bottels of Honda all season anti freeze type 2, without mixing water) as in if the radiator has had a shock as it is used to plain water ! Ha ha.

also the plug cables need a replacement, could this add to the issiue ?

What do you guys suggest ?

Edit: its a non vtec

i think its obvious that i am running rich. How do i cure it

thank you. Will try that. Noob here, what is FPR may i ask ? Thanks.

=)

sorry i missed your post earlier, so thats fpr. Ill have to check on the ECU, not that i know how to 😀. Will look it up. My bad, i did not mention that it is Sohc non vtec. Will check on the link. Appreciate it.

thank you.

If no VTEC code is thrown, then a P06 ECU for a D15B7 engine is likely installed. But it’s still wise to check.
