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
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.
Hey, I got a 91' firebird 305 tbi that had the same exact problem...it's your speed sensor or O2 sensor....(or both)
No you do not , But it's one hell of a job to get off.
