Can too much Fuel Stabilizer cause engine to stall

[Enricor99]

Hi,

Just stored my vette for the winter by adding Fuel stabilzer (had to run the engine for 10 mins afterwards) and now all my engine does is constantly stall. Could putting in too much fuel stabilizer cause this issue?

How much is too much? If it's the recommended amount or even double or triple that- I doubt it.

Not likely. If this is a carburetor vehicle, if you added the fuel stabilizer and then did NOT run the vehicle for 15-20 mins or more before storing, then the varnish buid up in the float bowls probably plugged the idle passages. The float bowls hold so little fuel that it doesn't take long for the fuel to go bad, and even with fuel stabilizer added I have seen varnish develop and plug passages. If you are stating that this problem happened right after installing the fuel stabilizer, then the float bowls were probably already contaminated. Good luck with it.

It is a carburetor vehicle. I do think it has something to do with it . The car will not stall until I take my foot off the gas

I routinely let my toys sit for 6 months or more without using any Stabil and have never had a problem. Something else is going on.

I don't put anything in my fuel either...
never had a problem.

If it doesn't stall with your foot on the gaspedal, just turn up the idle rpm to that level and go for a drive. Lets say one hour, everything is then warmed up compleetly, all the fuel is flushed and maybe if varnish is the problem then fuel (maybe) will clean the inside carburator.

On the other hand, when you take the top part off the carburator you can clean most of the passages on the inside, always a good idea to do (if you know what your doing!)

Thanks everyone. Is there a spray you can use to spray into the carburator that may clean out the fuel bowls?
