Gm trouble codes 44 and 45


Code 44 is for the O2 sensor staying on lean, and code 45 is for the sensor staying on rich. The sensor is supposed to switch back and forth several times each minute if it is working correctly and the computer is controlling the fuel mixture.
The problem could be the sensor or a fuel problem such as an injector. The O2 sensor would need to be tested.

Do headers disrupt chevy 350 tbi performance


You might want to do a tail pipe pressure test to be sure your exhaust system is not partly plugged. I am assuming that you pulled the 02 sensor from the exhaust pipes or headers. The headers sound as if they have been on the truck for awhile and are not new to the unit so then I would not think they are causing the problem. But I tell you for sure the plugged exhaust system will.

Sounds like the fuel pump is going bad(or in this case,has gone bad). I suggest that you change the fuel pump and use a fuel cleaner in your gas tank as dirty gas may have caused the problem to begin with.

I am getting a code 44 lean exhaust on the left , Is it the tbi gasket?


No if it was TBI gasket, it would be idling very high, check for vacuum leak at vacuum hoses or in-take gasket, with a spray bottle with water, spray around in-take to check for leak, hope this was very helpful.

I parked my truck and when i went to fire it up it would not start. I know for a fact that my fuel tank switch is going out would this couse my fuel pump not to work. i Have a 1987 chevy truck with a 350...


believe it or not some came with a fuse for the fuel, I would check that first, for both of your tanks to be bad , well its unlikely, I would say a fuse, and if its not that you should be able to turn your key on and kinda lean down under the truck and see if you can hear the pump working , if you dont hear the fule pump and the fuse is good the pumps are bad

Trouble code 33 &44


Code 33 is MAF sensor (mass airflow sensor ) & 44 is lean exhaust mixture. My guess is 33 is causing 44.
