yes it is fuel injected.
91-93 octane premium
3rd Gen also. Follow the directions for a 91 & 92.
Yes, the 91 Dakota is fuel injected, throttle body fuel injected.
I calc'ed my '91 V8 Formula Firebird to be about 18 mpg.
A firebird can't "have" third gen. It either is or is not a third generation firebird, and Yes, a 1991 is a third generation.
You may want to check the fuel filter. these cars also have a fuel pump relay, I have the same problem with my car. have you gotten yours fixed yet? I'm just getting started on mine.
Yes
Fuel injected? In the fuel tank
Hey, I got a 91' firebird 305 tbi that had the same exact problem...it's your speed sensor or O2 sensor....(or both)
Probably If fuel injected yes
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.
you should check out the oxygen sensor.I had a problem like that with a Pontiac myself.
