Mura

ugh, since my last messgae didn't go through...now a short version. when ever I put my car in reverse, my idle drops, thus, my car shuts off. i was thinking it was the spark plugs since the car was sitting in the guys yard for 3 months, but someone from teamfc3s.org said it wasn't that. I'm also thinking that it could be the coils, but I could also be wrong. Another problem is the HOLD light consistently flashing. I did some esearch on this and founf out that I need to flus hand fill my tranny fluid. Is that correct? Anyways, These are the two main problems that I'm trying to figure out. Also, is it normal for 1st gears rpms to rise up to 4300 then shift into 2nd? any help would do.
