My civic has a bit of a "lurch" when the fuel cut activates and deactivates. It's more pronounced in the lower gears like one would expect, but I would really like to find out how to smooth this out if it's possible. It's had this little glitch since I've owned it.
What's been done so far:
Cleaned throttle body (gently).
Cleaned IAC valve.
Set TPS to .45v @ closed throttle.
Performed idle re-learn.
Checked for vacuum leaks (none found).
Replaced PCV valve (with Autozone part, factory Honda valve on the way).
Checked/adjusted valves
Replaced spark plugs (factory Denso) & air filter.
Any ideas are welcome; thanks!
