Ok I'm having very bad mpg issue's. ...on highway I'm averaging 13 and in city I'm averaging 12.5...I know I should probably do spark plugs n vlave adjustment....can anyone tell me how I get to an clean my egr ports and adjust my valves...please I need to do this asap..its gonna be warm today so id like to get it done today..specially cause its costing me a lot more in gas. I'm even filling up with premium gas.

I wish i took some pic when i did all this repair..but any how..to clean egr system..remove egr valve and upper manifold cover lid..and have a compress air ready to blast out the carbon deposit..

Search EGR valve cleaning. i'm sure there alot of thread covered about this issue.

2nd.. Spark plug change is easy front, rear is limited space but you manage !..

3rd.. Valve adjustmen need to remove valve cover adjust it to .22 and .30 specs. t for sure Intake valve clearance is off, cause your MPG to drop along with your egr port dirty.. Your car is probably not breathing efficiency..

Im not trying to be rude, but have you considered taking it in for someone to do this for you?

brandon23 · 01-31-2013, 10:48 PM

Brandon23.....you asked too much for most issue have been covered..reader misunderstand you If you a type of person who do everything themselves like you claim you do...It make sense if You should Google it up and search forum on "DIY" or how to do things...

Since you intend to work on your own car and you have the mechanical background, you just need to get a copy of the service manual for your MDX. You can buy one here. Manuals for 2007 and older cars are 25 percent off.

I was always taught u could never ask enough questions.... I had searched and searched and searched and the best information I could come up with was here asking you people questions. I thought thats what this forum was for. Or am I wrong? He may have misunderstood me but you would think if I was gonna have a mechanic do the work then I wouldnt be on here asking questions Right? Oh well anyways I appreciate the help from everyone specially you HTL. I got everything fixed and working well. Besides the vtm but I have to go purchase the sensor...This forum was very helpful
