Hey, new to the forum so bare with me now. Recently I've been having problems with my 94' pickup with the 22re. Keep in mind it is a freshly rebuilt engine with only 20000km on it. Almost 95% of the time it starts up perfectly with no issues, yet it occasionally starts and idles very rough followed by immediately stalling. I have no check engine lights, cleaned the VAFM connections and removed/cleaned the EGR valve and have noticed this random stalling still occurring. Any thoughts of what else I could try to fix this problem? Cheers!

 

Some things to check is to burp the cooling system, no vacuum leaks, valves adjusted, all sensors cleaned and I would check to see if the dash pot is operating correctly.

 

I forgot to say in my original post but I've checked the dash pot and cleaned the sensors. Although I will take a much closer for a vacuum leak. What would burping the coolant system do?
