Anyone here ever ran a 5.9A/F reading

[shane02pro5]

Check to see if there is a check valve on the vac line coming off the top of the intake mani just behind the throttle body going to the purge solenoid valve.

yeah I check and the valve is there, the only thing I notice is that theres a tiny crack on the vac. line that runs in the middle of the check valve n T.B. but I really can't inmagine how that would make a code for huge leak ether way i'm fixing it. Is it possible bor the walbro or something in there to be loose?

tiny crack in vac line = replace them ALL.

 

[shane02pro5]

Exactly a small vac leak can create huge problems!

 

[1fastms]

Well as of now my lines that run the W.G, B.V, BPV and gauge are replace. Which other lines can I replace?

 

[Wagonbacker9]

all the ones on the back of the mani, one that runs off the pass side...

basically, just look for lines coming off the manifold and replace them all.

 

[1fastms]

So which are really the best(stronger,last longer ) vac. lines to replace them all?

 

[msp tom]

Go with vibrant they sell little kits with every size line you will need. I replaced all of mine and still have some left over.

 

[msp tom]

If you think your fuel pump is "loose" check that also

 

[Wagonbacker9]

any silicone line. brand is irrelivant really.

thats cool, I will be looking for some silicone lines. I have try to search but no luck, n.e body nows where can I find a diagram of the vac. lines on a 626I.M on a msp? just so I can make sure the mechanic did it all right.

 

[1fastms]

Also does n.e one know for sure if I need to run a vac. line to the vic. sensors or not?

Theres a hose on the plenum P/side of that mani, One underneath by the plenum that runs to the brake booster, one on top and one on the D/side by the throttle body.With 626 mani, no vics/vtcs, so lines should be run to a "t" as in my picture. If you want you can cut those vics/vtcs sensors and cap the wires off if you don't plan on using them again. Also it's common to run a 5.9/1 or lower afr when cold, if it stays there when warm I don't think it will run if it's a true reading. Are the stock O2's still in place and being read?On turbo motor I think wideband should be at least 36" away from exh. ports, did you wire it correctly?

Replace all vac lines. Replace intake manifold gasket. Check your fuel pressure regulator. Grab a new throttle body. Test your maf with an ohm meter. Check for leaks after your maf

 

[mattxhand]

Just light a match behind your exhaust. You'll know if there's a problem ;P

 

[Wagonbacker9]

um... a match won't do anything. a blowtorch, maybe.
