Is the check engine lite lit?

 

yes the check engine light is on..... it turns on after like 2 mins. of running...the acceleration also bogs,it pops near mass air filter when reaching 3 rpm's.

 

You have to pull or flash the trouble codes (DTC)and it will point youto the trouble that the computer sees.
Flashing codes at DLC connector:
Turn key to OFF
Connect pins A & B together
Turn key ON, do not start engine
The MIL lite will flash code 12 three times (Flash, short pause, Flash Flash, long pause, repeat)
If there are any DTCs, they will now be flashed three times each, starting with the lowest number to the highest.
When all the codes have been flashed, the MIL lite will flash code 12 again, indicating that all codes have been flashed.
Now you need a chart to tell you what each code meant.
