balance rates...

[ZeroGravity58]

So today i was driving and my SES light came on. I got a code P0305 which was a #5 cylinder misfire. I pulled my balance rates....

In park balance rates are
#1 -1.44
#2 0.17
#3 -3.09
#4 0.66
#5 3.78
#6 1.44
#7 -1.38
#8 0.06

In drive balance rates are
#1 -3.45
#2 -2.63
#3 -4.44
#4 -0.44
#5 10.92
#6 3.44
#7 -3.14
#8 0.08

Everytime i got the code twice and it was at idle at a red light. Seems like maybe #3 and #5 are going bad on me. Any other ideas? I really dont have $1000 to fix this thing i just bought a house and I have a baby on the way.

injectors out of warranty join the club. just did my original 8 86,000 miles 7years 2 months old. got my bosch remans from midwest fuel injector 236 each. would only reach 71 when commanded pressure 160.

Is it possible this is not bad injectors? I would do a compression test

how would it be so diffrent from drive to nuetral if it was a piston?

they look fine and all in spec. looks like #5 may not be getting the pressure needed...idk.

In park they all are within spec...

Check the compression. Misfire could be coming from cam position which could explain balance rates also.
