So I have a 98 trans am ls1 m6. My problem with the car is I get a p0102 and p0103 codes. One is mass of air flow sensor low voltage and the other one is high voltage. I replaced the maf and the car still miss fires crazy. I see in my scanner that the car short fuel trim goes down to -30% and lower under light accelaration and cars misses bad. If I shot it down and turn it back up it will run great for couple more seconds. Any inputs?

Idk, I put my gauge on it but the hose that attaches to the rail is broken.

- fuel trim means the ecu is trying to take fuel away because I'm running too rich, so I assume the fuel pump is alright but a sensor is causing me to run way too rich.
