If your engine is ideling fast its probably temperature senser. There is no adjustment for idle.
that last answer is not entirely true. u can adjust the idle. but it depends on if its a throttle body unit that looks like a carburetor or a smaller unit. on a TBI unit, there is a screw u can adjust but the only way to adjust it is with the right tool. its not a Philips screw or straight blade. but if its idling high or fast it might be the idle air control valve. the one went out on my 1985 sunbird and caused it to idle funny.
all depends if it's carburated or fuel injected.
On most or all gas powered cars that R fuel injected from the factory, the fuel pump is inside the gas tank from the 1980's to present.
I believe that the fuel pump for the 94 Pontiac sunbird is in the gas tank.
It is in the fuel tank.
Fuel tank.
In the fuel tank.
yes it is fuel injected.
Standard fuel pressure for a 91 Pontiac Sunbird is between 50 and 55 PSI. This is the idle pressure to allow for maximum efficiency of the fuel injectors.
gas tank
About 14.5 gallons
Idle speed cannot be adjusted on this model. No manual adjustments available. Problem may lie in fuel pump, or fuel filter or temp sensor.
