h22a (JDM) motor with h23 tans.
cold air intake
header and full borla exaust

ok so im going be as specific as i can.. okay ill start by saying i already replace the dizzy cap, plugs, wires. and checked my vacum hoses and all are crack free. i check for intake manifold leak and there wasnt one. although one vacuum hose did seem a little big.


okay now to the problem.

my car starts fine every time and runs smooth and steady at 780 RPMs.
but when my car warms up(about 10 min. of driving) the car loses all power until it gets pasts4000 rpm. like it just bogges and lagges out. i can floor it and it still hardly accelerates... it doesnt run like an h22a should at all. but if its cold or the air cold outside. like a cold day. the car runs great it just had gobs of power..
i have heard mabye its my coil.. because it doesnt have a bracket and is sitting above the starter and gets hot..
i dont no what it is and cant find information.. PLEASE HELP ME!!!

ill explain in better detail whats happening while driving..

ill take off and the car feels really heavy and doggy untill it hits 3800 or 4000 rpms and then it hops a little bit then it runs fine. i also noticed that the exaust gets louder when this problem happens. also as im slowing down and stop at a stop light the idle will drop really quick sown to like 300 then back to normall 780 rpm.... once again please help thanks!!
