TEK945

First the tps sensor was acting up every time i let the car idle to long the check engine light would come on the air conditioning would stop getting cold and when i pressed on the gas the car would be making a weird bog sound the computer would read tps sensor i would erase the code and the car would drive fine again i finally replaced the throttle position sensor and the car drove fine for awhile and it could idle long with no problem lately the car just starts to bog out for no reason i would start up and drive around for a long time with no problem and out of the blue when the car reaches 3 to 4 rpm it starts bogin like crazy makes it look like some one who cant drive is inside it just bogs and goes bogs and goes and i either have to apply full gas and speed so it doesn't bog anymore or just pull over what could this be.

My Setup

D16 Y8

10.3 spark plug wires
irridium plugs
4-2-1 headers
2.25" exhaust piping
short ram intake
performance bearings was put in the engine when i caught a knock a few months back.

All help is greatly appreciated
