well damnit not all is well, idles crapy has a miss recorded it with datamaster

injector BPW at idle is 3.46 & 4.32

map reads 50 kpa

long term counts are 119 & 148

right side is out to lunch

O2s are new (napa)

also have a wideband in reading mid 15's at idle

where do i start?

opti & wires are new, plugs are 2 years old, no i did not change them


if i lean into it there is s noticable miss under say 3000 may still be there at higher rpm just not as noticable

thanks in advance

Maybe start with replacing what you know is wrong?

Any exhaust leaks/ vacume leaks?

shorter plugs did the trick, got the wires away from exhaust on right side

a/f will be lean at idle, I believe, its under throttle you will want to look at it

I'd change the plugs and look for an light show under the hood at night (arching wires)
