My cars been bogging out lately. Mainly when it hits around 3k rpms.. The cars pretty much sold but I dont want to sell it like this.. What are some common things to look for when trouble shootin it... Its a 00 si, I bought it missing the head and tranny, put those back on, it started doing it a little so I corrected the timing a little and its still doing it.. PLEASE HELP!!!

 

bump

 

check the spark plugs

 

IAC valve or tps maybe...
