between 1k and 3k my gsr will bogg bad. even if i give it alot of gas it wont respond till 3k and start picking up. it is a gsr. so it has not been swapped. i dont know what the problem could be.
this is what my compression test showed
1- 160
2- 165
3-168
5-171

i dont no if that will help with my problem but i did put octane booster in the car and it did not help. well any help would be great. thanks

 

check clogged fuel filter or if the fuel pump is going bad
