Greetings,

Having an issue with my 2000 Honda civic HX. I drove the car around and warmed it up, parked it in my driveway and let it idle. It seems to have small bogs or hiccups throughout the duration of its idle, like small drops in rpm that are a tad violent every 5-10 seconds. I've cleaned out the IACV about 2-3 months ago, all consumable ignition components have been replaced in the recent 3-4 months. I have messed with the tps before, could it be affecting this? (I would think high or low idle but not bogging.) Any help is appreciated. I also just recently completed a valve lash adjustment to spec.

 

when you say "messed with" what do you mean ?

 

I replaced it a while back (a year ago?) because I was experiencing extreme fluctuations in rpm while driving on the freeway. I don't know if I have it set at the correct voltage though.

 

you have to calibrate it.

Any CEL codes?

 

Understood. Would, it affect the idle like this after not being properly adjusted for this amount of time? It hasn't been like this and the tps has been in the same position. I also have an exhaust leak near the ca
t. Could back pressure affect it like this? I also read bleeding air out of the coolant could help? Also no cel atm, although it was on a few days ago but the battery was unpluged and the cel has stayed off since then. The code was due to a heavier wheel switch (hx rims to gsr blades.)

 

What codes were thrown prior to you resetting the ECU?
