I have a 91 2.5. It idles high at around 1200 rpm. When pressing the clutch while driving the rpm stays around 2100 rpm and takes a few seconds to go down. I have replaced vacuum lines from the regulator, MAP, clutch, PCV,. Replaced IAC, MAP and TPS. Recently replaced 02 sensor,dist cap and rotor. Radiator flushed and today I changed the oil. Removed and cleaned throttle body and checked for leaks.
O2 sensor brand is Spectra Premium
IAC brand is bwd
MAP and TPS is Crown
Upon close inspection I found a crack in the brake booster grommet. I will be replacing it tomorrow since I found it after the store closing time.
Anything else that I can check? Did I miss anything?
