Sounds like you may have a bad head gasket you will need to take it in for repair.

Chevrolet cruze 2012 spark plug gets wet with water from somewhere, it is not because of a wash, I did a pressure test the head gasket is fine ,,, they say, the blue liquid turn yellow

The cylinder pressure may be fine but the leak might occur from the coolant part of the gasket, possibly incorrectly tensioned bolts. Try replacing the gasket (at the very least do a visual examination) run the car for 20 mins with the hood up and watch the area closely around the plug area and note if any hoses are leaking nearby.

My 1991 cutlass cierra oldsmobile is not firing. i replaced the fuel filter fuel pump and the crank shaft sensor. After that it did start up now it is doing the same thing as before just turning over but...


Pull a spark plug wire and put a screw driver in the boot and lay it next to something steel on the engine, do you have a spark?

If so pull a spark plug and see if it is wet, like water wet. Are you low on coolant or loosing it?

These engines have a intake fail issue, the upper intake will not can, but will leak, when it dose it sends coolant down the intake and wets the spark plugs. Crank the engine over a few times before doing this.

The best way to know for sure is to remove the Throttle Body and look inside the intake with a flashlight.

You may be able to get away with removing the screen from the Throttle body with snap ring pliers and opening the butterfly and looking in, but that mesh is very hard to remove and install.

Good luck

Has to be coolant ,not water, water evaporates, if you use coolant and there is no leak, then the head gasket is damage or the cylinder head is crack. remove the spark plugs and check inside the spark plug hole for coolant, check the plug for wetness or white crust sign of burning coolant. good look friend.

Car cuts off while driving, what's wrong?

Check your coolant level, these engines 3800 II has issues with leaking coolant into the engine smothering the spark plugs under hard stops and or acceleration. Only removing the Throttle body and looking inside and seeing "wet" will indicate and issue aside from loosing coolant.

If your coolant is ok look into getting new spark plug wires and plugs as well a new air filter if needed.

Also run fuel injector cleaner.

Are you getting any waring lights?

Auto Zone checks them for free.

I hope this helps.

#1 plug is miss-firing.I have replaced plug and wire,but keeps miss-firing only on#1 plug.have been told that coolant is possibly getting in #1cylinder.also I have been told #1 coil could be bad.witch is...

Could only be a few things. The coil #1, Fuel injector #1, Stuck intake or exhaust valve, or blown head gasket allowing coolant into cylinder #1. Use a spark tester to check the spark coming out of cylindr #1 if checks good then ohm test the injector when it is warm. Check other injectors to compare. Do a compression test on cylinder #1 and test other cylinders to compare. If cylinder is low compression suspect valves and or head gasket. If compression is low then het a leak down tester to test if a valve is broke or sticking. On your sable i would suspect injector or coil most likely.
