Stumped A/fs 10s at idel

[talon187]

Ok i ended up changing my intake manfiold a month or so back and had issues every since. After i did that i found bad wires in my engine harness. I got another harness and just got it into the car the other day. i started the car up and ran for a min or two and stalled. Went to start it no good. Looked at the wideband it was at 10.0. so i unpluged the fuel pump cranked it a few times fired up for a min. I then checked the plugs back and soaked in fuel. I have no idea why. Im running a stock 1g mas for the moment with an eprom ecu set for my 780s and its program for a maf pro. i asked jeff from dsm chips.com and he said the 1g mas would be ok to run because i didnt want to wire in the maf pro yet. Ive checked for boost leaks and have none. ive also turned down the fuel pressure to like 15psi and it helped at idel but if i give it gas it goes right back to 10.0 im totally stumped. I know im def going to need to change the oil now because im sure theres alot of gas in it now. Im looking for any input or maybe somthing ive over looked thanks!

So did you hook the maf-pro up and try to pull fuel. In my experience with the maf-t setting the injector compensation is not enough. You need to tune it out.

the maft and the maf pro are TOTALLY diffrent i had a maft. My frist problem is that a coolant temp sensor wire broke and i didnt notice it. Once i fixed that the car ran ok but idel was alittle high along with it on the rich side. I found out that is because the chip is programed for the mafpro and im using the 1g mas. It make it even worse that i have a tial bov and its venting. thats why the car idels so rich and so high. ill be wiring up the pro this weekend. I didnt want to have to touch the engine harness i just put in but o well looks like i dont have much of a choice

I think you might have went too rich and fouled your plugs. have you tried new plugs yet or at least tried to clean yours up? Have you let your cylinders dry out the fuel that was in them? Set your FP to 37
