I have a 1998 Honda accord 2.3 and when I first bought it , it had issues shifting gears and it would rev up then eventually it would drop into gear. I believe its in what's called "Lmip Mode" because it will not rev above 4000 rpms and I changed the oil in it. a city mechanic told me to change the solenoids on the transmission and see if it works. so my aunt buy and sells cars so she decided to by a Obd 2 reader for $400 and I used it this morning and it read code p0706 transmission range solenoid and a bad wheel right front wheel speed sensor , it also reads valve timing malfunction code p1259 or something like that , right front wheel speed sensor reads p11-1 I know I need motor mounts. I want to know whats going to get my car out of limp mode first and whats gonna really be essenitial FIRST to getting my car out of limp mode and running to its full potential again, is there anything I can do that's a temporary fix for now until I get the money to make the repairs myself DIY. so wha

My car has 28000 miles.
