SMALL EGR HOSE REMOVED - What to do
SMALL EGR HOSE REMOVED - What to do
Hello, I had my fuel injectors changed out this week and I told the guy that I was having irregular idle problems and it just ran really bad. I know my idle problem is the IACV and will try to clean it to see if it helps & if not replace it. I also cleaned the MAF and throttle body and it does run better. I noticed that the small hose that is connected to the EGR was pulled off and had a screw in it. I searched the forum and people are talking about removing the complete EGR system and I am not sure what to do. Does having that small hose off the EGR the same as removing the EGR? What does the hose pluged up do? I also took the BPT off and not sure if I should connect the EGR and put the BPT back on. I live in New Orleans and they do not check anything do that is not a problem. I know I am asking many questions in this post.Sorry about that. THANKS FOR ANY SUGGESTIONS.
the bpt is needed for proper egr function. which small hose are you referring to? there are quite a few little hoses that you could be talking about.
also, what year of the 240sx are we talking about? That should have been included in the title of this post that is also mentioned at the sticky at the top of this section.

Re: SMALL EGR HOSE REMOVED - What to do (Peabody)
If its the small hose that would connect to the top of the EGR valve then its the the hose that opens and closes the EGR valve. If you have rough idle issue that are fixed by disconnecting and plugging this hose then it means that you EGR valve was sticking open flooding the intake manifold with exhaust gas at idle. removing the hose closes the valve, effectively making the car run with no EGR.

HI, Sorry about not saying the year. It is a 1990 and yes when I would start the car it was very hard to start and then black smoke came out for a few minutes. I am going to search to see if I can clean the EGR and then connect back the hose on top of the EGR and put the BPT back on.- Can I clean the EGR valve or how do I stop it from sticking? I also forgot to say I have removed the Aiv from the car. - Should I connect the EGR back up or just leave it alone?THANKS
Yeah, you can clean out the egr by dunking the lower part (not the saucer section) in some carb or brake cleaner for a little bit and then stabbing into the hole with a screw driver to get all the carbon buildup out. I'd also give the metal lines a thorough cleaning as well.
Not sure how the emissions testing is in New Orleans, but in places like CA, an EGR is crucial to passing smog tests. So if emissions are scrutinized, put back on your EGR and all that jazz after you clean it. If not, I'd probably just pull the egr system from the engine to make the engine simpler to troubleshoot later on when idle roughness hits you (and it will with an old engine).
