    1987 Firebird engine stopping and spitting at 130 kmph

    Hello people!
    Looked through the posts and didn't see any that would clear my problem.
    So the problem is that before putting my car to winter sleep, made a little fast driving, to make last fun, but when I made full throttle the car started to spit and stuggle when I reached 130 kmph. Spark plugs are new, spark wires are good. What could be the problem? Some say it's ignition?!
    Thanks in advance.

    ^^^If they do have a governor, it wouldn't be shutting it down at such a low speed.

    OP, have you checked fuel pressure? Is yours carbureted?

    It's a little hard to tell without actually driving the car, but if it was a spark plug/wire/distributor issue, it'd most likely show up at lower speeds as well. A clogged fuel filter would act like you descrbe, as well as a partially cogged convertor. Your car has a catalytic convertor?

    Well it's there (catalytic convertor), but there's nothing inside it anymore. The car was standing for about 5-6 years before I got it and started to repair and drive. And this problem started after one meeting where I tested the engines Hz - full throttle in parking - just gas to the floor.
    So I will check the fuel filter and ignition. Is there some manuals how can I find out if the ignition is positioned correctly?

    Probably somewhere online but I don't know where. You should look to see how to check the ignition timing on the car, to be sure it is set properly.

    Just a thought. You are not driving this car around with the 5 year old gas, are you? That will cause all kinds of problems, it could clog parts of the carburetor.

    Carburator could need rebuilt after sitting.

    The excellerator pump plunger would get hard after sitting in old gas for a long period of time in the old days..

    Put a new fuel filter in it. The housing is where the fuel line goes into the carb. It will cut out and do the things you mentioned when this happens

    Well I don't know how old was the gas when I started the car for the first time, but the fuel tank was half empty so added it with "fresh" 95 gas. And all these problems started after I had run ~ 10'000 KM. I think I'll start checking the fuel tank after 2 weeks. Twisted my arm 2 days ago, so can't do anything.
    Thanks again! And I'll give a message until have some news.
    Have a nice week!

    If the car had been sitting five years or one year the gas was nothing but trouble.the gunk that use to be gas was traveled to the fuel filter and may be the carburator. I would change the fuel filter.check and see if there is one in the fuel line and hope that there is one in or near the the carb.If so you may be in luck and only have to change the filters .If not, you may need to rebuild the carburator.Old gas will kill a carburator quick. If you have to rebuild the carb, Clean the gas tank also so you want have this to happen again.i'm not sure but there may be a filter in the fuel tank. If it is, you will have to drop the tank anyway.
