Causes

Effects

a vacuum leakcan causea rich mixture

too much fuel or not enough air(passive) can be caused byA rich mixture

the common thingscan causea rich mixture

several things(passive) can be caused byA rich mixture

So many thingscan causea rich mixture

a dozen or more thingscould causea rich mixture

high fuel level in the carburetor(passive) caused bya rich mixture

this guy leaking too much fuel vapors in the intake(passive) is caused bythe rich mixture

2 ) High fuel pressurecausesa rich mixture

Manifold or vacuum line leakpreventinga rich mixture

A fuel injectorcould causea rich mixture

defective coolant temperature sensor for engine computercausesrich mixture

Fuel level above 1/2will causea rich mixture

my steps did n't have a place for the PCV to flow throughcausinga really rich mixture

bad fuel injectors , sensors or a clogged air filter(passive) caused bya rich mixture

the Air Filter A dirty air filter ... the gascausesa rich mixture

e.g. dripping injectorscausinga rich mixture

the butter ... stirringto createa rich mixture

JH4DC53033canister vent valve leak in diagphramresultingin rich mixture

Dirty air filterscreatesa " rich " mixture

oil to be drawn from the crankcase into the intake manifoldcausingan over - rich mixture

too high a level in the fuel bowl though(passive) caused byrich mixture

Anything elsecausinga rich mixture

additional fuelto createa rich mixture

Heating automatic valve is in start position and the enrich valve ca n’t be closed automaticallywill causeda rich mixture

So far I ca n't think of another reason ( other than high fuel pressuremight be causinga rich mixture

stuck distributor advance weights , and a warped Holley 4bbl castingcausinga rich mixture

Fuel injectors that are worn out can " slobber " fuel into the enginecreatinga rich mixture

But because all that air is n’t being supplied into the cylinders , the PCM is supplying too much fuelcreatinga rich mixture

engine knockcausinga rich mixture

the problems I have experienced andcan causeover rich mixture

Another thingcould causea rich mixture

Theonly thingcan causea rich mixture

that it maybe over oiled and its acting like a dirty filtercausinga rich mixture

dirty mass air flow sensor (causesrich mixture

When you refuel fuel vapour is pushed through the leaking valve into the engine intakecausingan over rich mixture

a fuel pump issuecausinga rich mixture

Fuel pressure that is too highcan causea rich mixture

add fuel accordinglycould createa rich mixture

the fuel pressure could have beenhigher causingrich mixture
