Low idle 240
I feel like I’m becoming a regular on this forum😂. So my 240 has had a low idle since I’ve had it for the past 3 years. It wants to be at 500 rpm, no more, no less, no idle surge, no rough idle (other than a few seconds after cold start). I’ve done everything I can think of. Vacuum test, fixed most if not all vacuum leaks, cleaned and serviced the IAC. Recently I did a major service, replacing whole PCV system, cleaning EGR and intake manifold, got the head machined and valves serviced, new head gasket, etc. So long story short, I feel like I’ve serviced anything that could cause it lol. I have an 89 b230f that has no idle adjustment screw. I’m wondering if it’s possible there is an error with my cars computers or something, just seems weird that it idles perfectly at 500rpm. please LMK if you have ideas, thanks.
