I am having rough starts and engine bogging / stalling issues.
I've done a great deal of parts replacing and at this point I feel I am chasing my own tail. Recently after doing a KOEO test and getting code 223 & 224 I replaced my ICM. This cleared the codes and my check engine light but now my engine is bogging and having a hard time starting, at a frequency of every second or third start. I checked my fuel pressure and with the ignition on only got it up to around 8 and running was around 20psi, which bumps up to 30 with the vacuum hose off. In protest I replaced my fuel pressure regulator and fuel pump and now my fuel pressure reading is 20 with the ignition on and 30 ish with the engine running (I believe it is supposed to be 40). The fuel pressure drops about 2 PSI over 20 minutes with the engine off.
A few other notes / potentially confounding factors:
- engine has white smoke on start up that seems very wet (not coolant)
- I recently installed a catch can into the PCV line
I tried a KOER test this evening and was meet with the code 411 which is "cannot control RPM during ER low RPM check". I cleaned my IAC and tested it by listening to the idle with and without it plugged in and it seems to be working properly.
Anyway, I would be very grateful for any suggestions on where to look to fix my hard start + stalling issue. I don't have very much experience working vehicles so any and all input is welcome!
