Um, Vacuum leak?

 

i don't think its that all my vacuum hoses are connected.
does anyone have a picture of where all the vacuum lines go and how they are supposed to be connected? my map sensor is connect differently then on my brothers teg when i connect it the same way his is the car idles very low and starts to boggg.

 

There you go brotha! Good luck!

 

thats how my map sensor is connected. is that the correct way?

 

no its not, look at the diagram i posted

 

^ yeah i don't think thats correct.. try that diagram db1posted.. if that doesn't work.. your air idle control valve should be replaced. thats what was wrong with mine.. i had pretty much the same problem.

 

did you reset the ecu after changing the map sensor?

 

yeah i did reset it..i changed the ecu too.

 

try this if this dosent work then im cluleess https://honda-tech.com/zerothread?id=1844067

 

dude,if ur car is reving to 2500k ur lucky all u have is an engine light,damn,what setup are u running?

 

nothing special..aem intake and exhaust.

 

video posted.

 

Tried swapping out the IAC valve on the back of the intake manifold? They tend to get stuck and will make the idle lope. Easy to bypass if you don't want to replace. Possibly not directly related to trouble code, however.

 

i am about to replace it soon to see if thats the problem.

 

is there any way you could send me pictures of all the vacum hoses and the map sensor?? am having problems connecting it....my car idles a lot...i put a ls on a eg

 

i will post pics tomorrow when i can get some pics ive also had bad throttle body gaskets do the same thing try it out for a few dollars at the parts store.... u could also get a can of carb clean and spray for vacuum leaks around tb and intake.... let me know how u make out ...w ill try to post pics asap

 

how do the vacum hoses connect..i have a eg and i put a ls on it.....it idles a lot...i need to know where the map sensor and all the vacum hoses go to..
