So i have a few problems with my FD. First, it has a very rough idle once its warm. It almost sounds like it isnt firing properly, but i dont think thats it, i just did a full tune up on it. Also, when i left off the gas after accelerating or even jus reving the engine in neutral the rpms drop to like 100-300 then the engine "cpmes back to life" to about 1k rpms then drops back down to 800ish and just has a rough idle. Also, its running super rich. Like when ever i drive i can smell the gas bad. I am thinking that the map sensor is going out but i am not 100% sure. I dont want to go drop 350 dollars for no reason. If any one has any input, please let me know. Thanx for the help in advance!
