Ive Checked the EGR valve to see if there was any carbon build up. The area where the EGR valve seats seems to be fine. I don't see a whole lot of build up.
I've checked all the vacuum lines to see if they were plugged. They seem to be clear. I've also checked all the vacuum inlets going into the throttle body for any heavy build up. I found that the line for the PCV valve had some heavy build up, but was able to clean it out with some throttle body cleaner.? Would a worn pcv valve cause this problem. The reason i'm asking is because when I pull lose the pcv valve line off the throttle body the idle seems to smooth out quite a bit and the idle comes up just a hair. How would I know if the electronic vacuum sensor is working properly?
I've taken some throttle body cleaner and sprayed the surrounding areas of the EGR valve really good and also cleaned inside where the valve sits. The inside of the throttle body behind the EGR valve did'nt appear to have alot of carbon- just minor amounts. I sprayed throttle body cleaner into this area just incase there was. I also sprayed the area around where the injectors spray and around the IAC
valve and just about any where else I thought that minght be effecting the vacuum air flow. It's still idling rough when its warm but seems to be trying to run a little better that's why I was asking if the pcv valve might have a part in this. That's why I'm also asking about the electronic vacuum sensor. You pull the vaccum lines off and I've got vacuum on one side but not the other. Oh! The egr valve does seem to be moving fine but, it does make a slight rubbing sound.
I'm working at it little by little but, I know that the issue will be terminated eventually.
