Gas in spark plugs 99 izusu rodeo?

Question

i have lots of gas in my spark plugs and is fouling them out every 300 miles. When I try to crank it for the first time of the day and it shakes really bad and sputters. I have to force it to crank. But after it idles its fine any one know what could be going on???

Answer 1

If all the spark plugs are fouled, then it is probably a bad 02 sensor or even coil pack (something that all the cylinder shares).

If only one or few spark plug is fouled, then it could be stuck fuel injector (or single spark plug, wire, etc.)

Good Luck...

Answer 2

It sounds like your fuel injectors are leaking down.  Hook up a fuel gauge and see what the pressure is when running, then turn off the motor and see how fast the pressure drops, It shouldn't drop more than a couple of pounds over an hour.
