The idle on my Y8 is really quite rough. It dips between 600-750 all the time, and when I take it out of gear it drops to like 250, then slowly climbs back off, shaking and making weird vibrations. It runs perfectly smooth when I accelarate, it's just when it sits and when I take it out of gear and coast. Once when it was idling at around 450 it kicked up to 750 and smoothed out. What could be causing this? I think my cam/crank alignment may be off, is there anything else I can check as well?

try retarding your timing to help fix it, it might help.

 

Yeah see, I think the cam may be a tooth off, so that could be the problem, right??

 

anyone else???? timing didn't help...

 

yeah cam to crank may be off. also check vacume lines, idle adjustment screw, evac, coolant temp sensor and coolant level. fixing broken honda idles suck

 

Thanks for the help Tortex... Also, when I drove it home from work at like 1:00am it was running pretty well - the idle didn't dip, though it was still a teensy bit rough. It was great compared to earlier in the day. I fiddled with the cam gear and it didn't help, same with timing, but I'll check my vacuum lines and idle adjustment screw as well. I think I may do a valve adjustment too.

How do you check the evac and coolant temperature sensors, and why would the CTS affect the idle?
