Default Pulled codes and...

well I finally figured out how to pull codes using the jumper wire and check engine light...

I screwed up the first time and accidentally clearr them from memory...

but,

first it showed code 11, and I thought I was in the clear..

then it pulled the codes from the memory...

and here is the laundry list I got...

29, 33, 41, 91, 95, 96...

looking on troublecodes.net
http://www.troublecodes.net/Ford/

29=VSS, vehicle speed sensor (I guess this is why my cruise control has never worked...

33= EGR did not open/non responsive (BAD EGR???)

41=System lean (this worries me)

91= system running lean=fuel control

95=fuel pump/ open, bad ground or always on (I dont know, does that mean my pump isnt working right? its a brand new Walbro 255....

96=fuel pump monitor circuit shows no power (what does that mean? the car runs)


where do I go from here? obviously I need to clean/replace my EGR, can I remove it and plug the hole and suffer no problems? will the ECM delete its function?

the running lean issue scares me, should I replace the fuel filter, run injector cleaner through it? do I need a new FPR? and where is that located???

any help would be great, thanks guys

make sure you have no major exhaust leaks prior to the 02 sensors. make sure the 02's are seated in the bung all the way. if both of those are fine then check the HEGO ground strap. if that is fine you can either take the time and test the 02's or just replace them.

egr, if you dont have emissions just unplug it and delete it with a block off plate.

what is the HEGO ground strap?

I dont have the sniffer test.. Ive always just gotten a sticker. my mechanic doesnt do jack haha

plus if the dumb thing is broken and a new one costs like 130 bucks, screw it... haha

now the o2s would be the reason my computer is telling me I am running lean?

yes. 02's are mainly responsible for sensing lean conditions.

HEGO ground strap is a orange wire that is generally bolted to the back of the driver side cylinder head.

I'll have to check it out, I assume I am just checking the ground for corrosion?

exhaust leaks can be detected by smell/feeling for escaping air? and a popping noise right? I'm just curious, I never had an exhaust leak before... on my old car, the exhaust pipe pretty much just fell off when I hit a pothole ones... haha

yea you pretty much got it. you dont need to search all the exhaust. just make sure its nothign major around header gasket, connection to the downpipe and around the bung of the o2 sensor. also make sure the o2's are plugged in and fully seated into the bung.

for the ground strap, just check for excessive corrosion, make sure its connected, make sure the wire isnt damaged around the eyelet where the wire is crimped.
