My 2004 se sedan 2.0 zetec dohc was having idle issues so I replaced the iac valve, took forever but got it done on ramps. It idles fine now but it sometimes gets stuck at about 1800rpm when I’m driving slow. I replaced the hose from the egr valve to the intake manifold and the pcv hose to the intake manifold. I’ve also cleaned the throttle body and the maf sensor. The throttle body “door” snaps back and opens easily so I don’t think it’s that. Before I replaced the hose from the egr valve to the intake manifold it had a code p2195 with no engine light but I cleared it and it hasn’t come back so far, I’ve driven it maybe 150 miles since then. Any ideas on what to check next? Should I just replace the o2 sensor and the tps sensor and see if that fixes the issue?
