    Get your car to a mechanic. You shouldn't have problems like that from switching to gas 1 octane point lower when you don't need that high of grade to start with.

    Would you describe the noise it's making and where you think it's coming from -- maybe open the hood and listen?

This is not a problem that was caused by your gas. This most likely just happened at the same time. It sounds as though you now have a blown head gasket. one way to check is pull the oil dip stick and look at the oil. If it is a milky dark grey color then there is water in the oil and you have defiantly blown the head gasket. If the oil still looks ok then have a mechanic run a compression test. The overheating was most likely caused by a faulty thermostat or low water in the radiator. The compression test will tell you definitely weather or not a head gasket is blown. If this is the problem then it could cost somewhere around five(5) to eight(8) hundred dollars to repair. Another sign of a blown head gasket is a very rough idle. Hope this helps. Good luck.

The chances of the very minor octane change causing damage like you are describing are so slim they are non existent.

Your overheat problem just happened to coincide with this fill up. If you have motor noise that sounds deep and thick like a hammer inside the motor or followed by a chirping sound you have already blown the motor.

I would start pricing a motor and know that under no terms did this difference in fuel octane (if it was good fuel) cause this damage.

What powers the injectors on a 92 chevy caprice


They are powered from the ignition switch (12volts). There is a fuse for them. When you turn the car on one wire at the injectors should have 12 volts. The other wire goes to the ECM and the ECM is what grounds the injectors to open and let fuel threw. This can be checked with a noid light or a volt meter.

I have a 92 chevy caprice that seems to have no power to the injectors what should i do?


You need to keep testing the wire back till you find power and fix what ever is stoping the power from getting to the injector.
The power for the fuel injectors comes from fuse 11. Fuse 11 gets it power from the ignition switch. The wire at the ignition switch is pink. The power going to the ignition is a red wire witch come from a fusable link.

How do you get an air bubble out of a 1994 chevy


You would not. All air in a fuel line will come out when the fuel pump is pressurized. I assume you have tried pumping the gas pedal? Also try depressing the pedal halfway down when you try to start it, if not press all the way down and try. You may have bad gas in the line or a blown fuse for the pump. It is very likely that the pump may be bad. But there should not be any issues with air in the line. You could possibly also have bad fuel injectors.

No power tp the fuel pump, injectors not pulsing, no fuel.


Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.

Also do not let tank run low because fuel in tank keeps in tank pump cool. This is why the pump is in the tank.

Cutting off while driving


Try checking fuel pressure again with a guage on the fuel rail. If you still notice the pressure is low and you know the fuel pump is good, the fuel pressure regulator may be bad. Sometimes you can tell by unplugging the vacuum hose from it and if you see gas that means the diaphram is leaking. If everything checks out with the fuel system a bad EGR valve or EGR valve solenoid can cause cars to sort of stall under half throttle. Good luck and keep me posted.
