Klze runnig rich at idle?

Post by hgallegos915 »

Oks.. my ze had bad intake manifold gaskets.. corrected it.. now the afs are weird..


its normal under cruising.. normal under WOT...

but AT IDLE its rich.. like at 10.1 and it makes the car stall.. so i played with the afs, i made my fuel pressure at 25 and it kinda helped.. 12 afs.. but at idle? o.0


new spark plugs, (from the faqs) cables are good(a few months old)

I have a kl36 ecu.. cant check codes as i lost the cover that tells you which one is the FEN pin.


I have been adviced it can be the fuel filter?



NOW i do have a WALBRO 255.. will that make my car run rich at idle?

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

I would think unless you had an AFPR then yes it would make it run richer since you are pushing more fuel but I am not for sure...

You need an AFPR with a 255 Walbro, or you will run rich. Id suggesst an Aeromotive AFPR
