Ruff idle with fan on - Futaba 1997-2006 Honda CRV Radiator - Futaba

the clicking noise will be a relay working so find it by feel and you will have the problem source. You will then have to find out why the circuit to the relay is intermittent to cause the clicking

Tune up ,fuel filter,air filter,IAC sensor,dirty throttle body,wires,coils.

This seems normal to me, but you can try removing the idle air control valve and cleaning it to improve responsiveness.

you have a bad temp sender,if this does not solve the rough idle than you have multiple issues and your idle control valve is not functioning properly try removing and cleaning it.its also referred to as IAC (intake air control)

It is most likely you wheel alignment (costs about 20 bucks to have your wheels aligned) or try checking the tire Pressure to make sure they're all even maybe hope this helps

Could be a wiring problem or plug problem, which should be checked first. If they have been changed, it could be a cam lobe bad...worse case, least likely.

use carb cleaner spray on the inside of the throttle body.

use super unlead only to prevent buidup.

cold engine only.

hope this helps
thank you

You need to determine why the fan is on (stuck relay, bad sensor etc.) If it remains on, the computer keeps engine controls in "cold-start" mode and will not operate properly. (re-check codes after the fan works right.)

ruff idle may b idle controll senc. ----tapping may be plugs-- wires, and or gas try 91 oct gas next 3 tanks and see thats the cheeepset place to start

Hi you should change the coolant temp sensor this is a white sensor on top of the intake and is part ot the computer system.
