so i have a used c2 stage one chip red top bosh injectors 3inch dp back exhaust 3intake with a 4inch maf up front 2.5 intercooling pipe running a dv recirculated but doesnt matter car is dumping fuel on idle. it is literally pooling up on the exhust manifold i took the dp off and its spitting out turbo like daffy duck screaming what would cause this wile installing turbo i removed sai plugged hole removed the gas evap can installed a short runner and a clutch car ran fine before turbo install i do have a code p0131 low voltage bank 1 thinking about trying a known good o2 sensor will a bad o2 cause it to run this rich? i have tried to search and fix this on my own all day now i need help maf is on correctly for sure
i started the car up tonight for about ten minutes it smoked and continued to leak gas through the exhaust i did retreive a code for a missfire in cylinder 3 i also checked the injectors and all chekced out at 16.1 ohms car idles at 820-900rpm and the boost/vadc guage reads 18 at idle it idles pretty consistantly but just loads of smoke and exess fuel some one said maybe coolant temp sensor will that throw a code or no i need ideas im stumped
now im getting codes for misfires drove around the corner to get some gas in the thing still runs like poo gas leakin through the gd exhaust what type of problems is this im thinking maybe the ford coil im using is bad all of a sudden why the miss fires this is getting worse and worse
Your plugs are most likely fouled out, I'd put in some new NGK BKR7's. The new o2 sensor could have fixed the problem, but if your using the same plugs there is a chance they are fouled from too much gas. They are also the least expensive part to try out so I'd say try this first.
The ICM could have gone bad also. Not sure if there is a specific way to test it, I just bought the cheapest coilpack on ebay to test whether mine was the culprit or not.
You could also try new wires if yours are old, can't hurt.
If the plugs were new theres no reason to toss them. Pull them out and burn them off with a propane torch.
Pull plug leads while its running see if your loosing spark from the CP, I doubt its the issue.
Forced convection.... Now we grillin.
Some times she goes, some times she doesn't.... Way of the road

Sounds like you might have a misfire and the car is falsly correcting for lean.
A new o2 sensor will react quicker at first, until it gets fouled out and slow from mis-correcting towards making an already rich condition even worse.
Did you check to see if the coil, plug, and ecm wiring is propery set up?
whats the ecm the ecu ? i looked briefly at the plugs in my harness at the ecu and the main harness for the motor they looked good no corrosion or bent tabs. i had a leaky injector seal when i first started and ran the car initially it was leaking from the third injector from the right badly. i did let the car run a little with this condition and the next day i went and bought new seals which stopped the leak. i replaced my o2 with the rear o2 i cut the plug and spliced onto the front o2 (im broke right now) i put in new plugs prolly put 30min of run time on them and its pretty much running the same threw a random misfire code and cylinders 3, 5
so after thinking about this is it possible that running my car while that injector seal was bad created this problem and the ecu needs to adapt now that the injector isnt leaking im thinking this because cylinder 3 is the one that misfires which had the bad seal before
Oops, I meant to type Icm, you wired in ford coils but kept the stock icm and had to wire them together, right?
you did put the c2 chip in the engine controller ????
that would run stupid rich if you didnt. i did that on my 16v with the c2 chip and it killed the plugs like right away. what is your fuel pressure at? i tried more pressure with my c2 chip and it really got alot of fuel at idle.
with great power comes great responsibility......so push the gas pedal to the floor
so today i got a early start all plugs looked black exept cylinder 3 which was wet and shiny cleaned plugs let cylinders all dry out i checked for spark with a inline spark tester and cylinder 3 was def firing consistently changed gap from like .040 to .030 car still runs the same slightly better still misfiring only cylinders 3 and 4 mostly 3. i ohm checked the coil on the car (not sure if i should have removed it i did unplug it) and all readings between pins were the same 6.8 or somthing could it be bad wires they look mint if its not the plugs or coil why is 3 missing?
3/4 might be firing, but did you see how all of the sparks looked in appearance to each other?
If you are sure that the HT wires are ok and no ground problems anywhere,
then it sounds like something in the icm, the 3/4 coil, and/or maybe the wiring between them.
Hint: Always check for boost leaks.
3 had a bad injector
which i went down to the junkyard and grabbed a set of four from a saab and the number 4 wire plug was broken so i swapped that too now it purrs rather growls i gotta get a muffler this 3 inch nonsense is too loud for my taste sounds good tho but too much of a good thing lol thanks for all the help i did find a super small boost leak too but i used like 20psi of pressure im sure its not bad at all with my 5psi wastegate
