I've had an 86' Trans Am for a few years now. Bought it off a guy who threw in a LT1 block from a 96' Trans Am, everything else aftermarket and carburated. The car has ran absolutely perfect and loud since I got it, until about a month ago. We had a huge storm and my T/A was flooded up to about an inch below the fusebox. Ever since, I have had issues with it starting and stalling. As for the starting, I have fixed the issue by cleaning the starter cables. The stalling issue was fixed by replacing a bad fuel pump (coincidence of the storm, maybe) but now I'm having problems with high idle in the mornings and only the mornings when I go to work. I live in south texas so temp isn't an issue, but after it's warmed up the idle will not drop lower than about 1400 RPM. However, in the late afternoon my T/A starts fine and is warmed up and ready to go at about 700 RPM in a few secs. I have noticed it has been really humid lately, my car is kept outside and nearly soak in water from the moisture. will humidity affect my idle? Thank You.
