If I lived in the suburbs of Chicago... then I could come over and help you out... but it sounds like you might have a cooked coil.

 

a:make sure you didnt blow fuse for your port...should be reason why scanner doesnt work..i believe its same fuse as your....cigarette lighter

 

i live in aurora, same thing but,,,, if it makes a diff, about 3 months before this started happening, i started getting like 8 to 10 mpg,, at 70dollars to fill up its really tickin me off, is there ne thing i can try tonight to see if it will help, would the cop explain all the black goop.?

 

First priority - Check your fuses , you need to get that port functional.

 

ok.... i checked all of the under hood mini fuses and cleaned everything, tb, IAS, all the intake ports. i used name brand tb cleaner for all of it. it looks spotless now. idles better, but still mid rpms are horrible. the IAS is clean but makes a noise when i push it up and down. dont know if it is still gummed up. i disconnected my batt so i have no codes or can tell if that portion works.. yet untill tomarro when i get my scanner back from a buddy. any more suggestions, The dealership said it could be anything from the fuse being blown to my Ecu fried, but that could be them just tryin to get me to bring it in there..... i am a certified mechanic, i have all the tools but this is stumping me.

 

im going to hook a vaccume pump up to the egr valve and see what kind of numbers i get.

 

Take it over to Autozone or Advance and get the codes read - they do it free.

If you are a certified mechanic, why the hell are you letting Jiffy Lube work on your truck? You should know better!

 

can you not read??? i cant scan it because.......SOMETHINGS WRONG WITH A FUSE OR ECU. people like you are reasons that people dont bother posting there problems...IDIOT

 

WOW slow down newbie... GLC is an awsome sorce of knowledge..... You dont want to tick him off. Did you check the fuses under the dash too? I know you mentioned the ones in the engine compartment.

 

If you got the low end back but are losing it in the midrange you may want to consider replacing the COPs. A low grade misfire does not always throw a code.
