Hi guys, i have a 92 rs 305 which has been giving me fits here lately, im gettin a code 33 and 54 from the ALDL.When car is first cranked up it fires right away and has a rough almost Cam'd out sound to it then it smooths out and throws a SES light as it smooths. I replaced the Map sensor and it had no effect on the idle or the bogging down feel.I decided to unplug the map sensor and it cranks up and idles smooth as can be.Im no mechanic and this is my first third gen so any input on where i should start would be awesome.

 

Not sure... you got high voltage at MAP code33 and you got low voltage at fuel pump code 54.

If I remebered correctly. You can check out all the codes and get a .pdf file specific for the engine at:
