I've searched everywhere and it seems a couple others have had this issue, but never really update on a fix. Ive posted about this before, but noticed something new. My car has a rhythmic surge at idle, you can hear it change in the exhaust note. Just yesterday I noticed a loud clicking noise in the engine, which initiates the surge. The sounds is coming from the throttle body itself. At first I thought it was the purge valve, but I peeled the intake coupler back just enough to see inside and visually saw the valve in the tb move with the tick.
My question is, is this tick normal? I can order a new tb for $180, and leaning toward it unless somebody can confirm theirs does this as well, or that its normal operation. It does it every 8-10 seconds. The exhaust note changes, and the vacuum gauge slightly moves. AFR is anywhere from 9.2-10.2 and goes up and down in rhythm as well. (e85, and yes I tested it). I put it back to factory with the factory airbox and 93 fuel and it is still present. Already cleaned the MAF and changed the plugs.
