91 Firebird, Question about a...

[strongdude85]

...Sensor? Hey. Got 1991 FIrebird 305 V8 TBI. Well the other day my car was running like crap, I pulled the engine code, came back 15. Coolant temp sensor. Well the car died, and I got it going again for some reason the gas gauge is broken, and it started again w/ new gas. I replaced the sensor, and just driving now the light came back on and it almost died at idle and was tough to start. Any idea whats goin on here? I know the sensor is why the car isnt running great.

For sure it isn't the coolant temp sensor.
The codes are for emission control...Pull all you want. No sensor on a 1991 is going to cause a car from not running.

Start thinking control module on the distributor.. Yank the cap off and replace the module with the grease that should come with it. Gently of course. Try it....!!! Easy to replace....relatively cheap....(20-40 bucks)....

Get it running ....then pull all the codes you want to diagnose the emission sensors.

That would explain all the info you have given.

OK with the first posts you made the coolant temp sensor could very well have been the reason it was not running correctly ..BUT I also said you need ed to check the plugs (replace them) and also check the O2 sensors as running for any length of time with a rich condition will foul them out causing it to run bad also ...
the best thing for you to do would be to spend a couple bucks and go have it properly diagnoised
if you keep throwing parts at it you are just wasting your money
if you have not replaced the plugs and the coolant sensor I would start there
I have seen it many times in cold weather ..
