Diagnosing a misfire
Trying to chase down a misifre at idle. No codes, runs smooth everywhere else. You can hear it miss and sputter out the exhaust.
AP2 engine on AP1 ecu.
Tried map whack. Checked plugs. Only other things I think are next is coil packs and injectors but I don't have any spares to swap with. Anything else I can start testing/trying?

I had a similar 'issue' -- it only happened at idle..
I replaced pretty much everything (valve adjust, leakdown was good, replaced coils/plugs/MAP/TPS, got injectors cleaned) and then gave up.. I eventually got an EMS, ID1050x and a SC and problem is gone so I think it was either injectors or ECU
btw I think I actually got the MAP sensor from you via pizza boy
