I've got a 1989 Trans Am with the 5.0 TBI motor. ever since i bought it, the check engine light comes on after driving 5-10 miles over 45 mph. I put an open element air cleaner on and moved the air temp sensor to the front of the car behind the drivers headlight. I've replaced the baro sensor, knock sensor and air temp sensor. When i check the computer, i get a code 32 and 43. any help is appreciated.

On another problem, my hatch release button doesn't work unless the key is in the off position and the brake light comes on when it is pushed. the release works, but the motor doesn't. Do i need a new motor?

One more thing, my fuel gauge only works from full tank to half tank. Do i need to put in a new pump or just find the right sending unit?

Thanks for any advise given.

 

The hatch release has a switch on the shifter that will only allow it to work in park and neutral.
There are several things that could be wrong with the pulldown motor assembly. They are notorious for breaking. Hawk's has replacement parts.

 

The switch on the shifter works fine, the car needs to be turned off in order for the release switch on the dash to work.
