What can cause the driver side floor board of my 1993 Cadillac Eldorado


If you have been running the AC for a while and the humidity is high, the condensate drain tube is plugged which will cause water build up to eventually leak into the passenger compartment.

TID saloon. Why is it lumpy on low revs?


White smoke is usually gas. Black smoke oil. It's probably flooding, injector or computer problems. Luckily, it sounds easily fixable at a good shop. A code reader will give clues, usually.

Well my jeep runs great when it wants but here latley its been missing but only when a rev it up or first started. iv been trying to figure out what it is but i dont know and its been fouling my sparkplugs...


no year car, no jeep modle . no engine told. (strike 3?)
is it a ww2 jeep?
get it serviced? ever consider that?

do you have a shop full of tools and know how?
flooding has many causes. and many tests.
ill not list them all , have done so many times.

MISFIRE. (Causes) google this words yet?
flooding, causes.
is fuel pressure too high,? you dont know.
are injector leaking, (you dont have the tool to do leak down and balance tests)
got bad spark , and no scan tool to see P0300 codes? p03xx ?
you fail. 1993 to now 1996 , has newer codes.)
flooding:
1: BAD ENGINE , compression bad, or vacuum bouncing. (runs great so...)
2: bad spark ,scan it yet.? give it a 60k mile tune up this decade?
3: bad fueling, (floods, for many reason)
4: bad fuel>?

2003 toyota sienna wont start sometimes But does turn over. Its not getting gas. After pumping pedal its starts


its not getting gas, is that a guess? or the results of a real test.
as per FSM book.?
the only test that proves not getting gas, is all spark plugs out and all are white and dry. (NOT GETTING GAS to the combustion chambers)
i think its flooding (sparks wet)
and all cars clear floods, with wide open throttle cranking, (A feature)
this magic feature, cuts all fuel cranking, to clear said flood.
(oper, guide covers this)

if this works,
ever consider a full tuneup? this decade? with filters?
if tuned up, then scan it to see if there are DTC errors cranking?
check for spark , during failures. ?
check for flooding? spark good,!
there are many causes of flooding, (spark good, tuned up)
  • too high fuel pressure
  • injectors leaking
  • fuel regulator bad.
  • no air supply starting, bad IAC STUCK CLOSED,
Try starting with 5% throttle ,creating a good human made, IAC, (fresh air)
each line has tests we do,, if you dont have tools, all this is just
water under the bridge.

do you want guessing (unsaid)
here:
  1. never tuned up.
  2. too high fuel pressure and flooding.
  3. and many more. i just rolled dice 2 times.

1999 mercury villager gas smell in oil


There are a number of possibilities here. Oil that is very old (high mileage) will become hydrocarbon contaminated over time. This can have a gasoline-like smell. There could be a problem with the piston rings allowing fuel the run down the cylinder walls into the crankcase. This can also occur in an engine that has a misfiring cylinder since the fuel is not being burned. Lastly, a leaky fuel injector can be flooding a cylinder, either when running, or after vehicle shutdown and before the fuel pressure bleeds off. This fuel will lay in the cylinder and eventually leaking into the crankcase, contaminating the oil.

I took my motor out of a 2003 sunfire and installed in a 2004 sunfire, ran good in other car but is flooding mad in the 2004 ,puzzled


Usually a flooding problem is a shorted fuel injector or a leaking fuel pressure regulator. Does it happen if the injectors are unplugged ?

My jag smells like as if it was flooding when i try to start it, when it does start it idles fine but as soon as I rev it up it bogs out, please help me as i really can`t afford to take it to a mechanic,...


Well first off what year and kind of Jag is it?That will make a difference on what might be the problem.If it is a carbureted model, it sounds like you either have a simple fuel line leak going to the carb so when your car sits fuel drips out and gives you the gas smell and then sucks air when you rev it up.If there is no line leak,sounds like your float in the carb is sticking open and simply flooding the carbs with gas,hence the smell and the bogging out at rpm.You would need a carb rebuild kit with float to fix that problem.That way you have gaskets and floats to fix your carb.

99 mercury sable automatic trans vehicle idles very low randomly even stalls out sometimes high idle occurs as well reaches about 4000 rpm at times. engine light threw 4 codes, all to do with o2 sensors...


Sounds like a broken or torn vacum hose, pcv valve clogged, or bad Idle air control motor. Did you spray carb cleaner on vacum hoses or near the plastic intake., and did the motor rev up or down? Those codes represent a lean condition which means most like a vacum leak or clogged idle air motor. Sometimes the intake manifolds crack or the intake manifold gaskets crack. FInd that vacum leak or inpect iac motor
