Can anyone diagnose a possibly tune related issue?

Alright, 103's are a tad cold... You could try AL 104s or Factory iridium plugs. Do not get the platinum ones, the car hates those lol

OK, I'll swap them back out with the 104's and see what happens. Any particular gap? I always used .053.

you can try 60, 55 53, and so on. 0.50 felt best in my car. but they are all a bit different in what they like.

Honestly man, I forgot what I gapped to last time. Google around or ask in the chat box.

Contrary to what some believe... a case learn is ONLY to get the KR monitoring and misfire monitoring systems working correctly and accurately.

Get us a basic scan of the startup and warmup. If possible make sure your wideband is logged as well (Incredibly useful). Then we will go from there.

Thanks for all the replies. I'll post a scan late tonight when I get home, the wideband isn't installed yet, gotta do exhaust work for that.

Edit - any particular parameters? I did basics (boost, baro, inhg, kph, kr, rpm, etc), but can do another scan if it would be helpful to have other parameters.

Commanded Afr, o2 MV, long term and short term fuel trims, timing advance, ect, maf hz, maf lbs, map psi..... Those things.

 

[nitehawkjcb]

Thanks Frosty. I'll do another scan, I'm pretty sure I left out MAF hz, maybe O2, and LTFT.

Basically whatever the default hptuners scanner does plus commanded afr.

 

[nitehawkjcb]

I'll see what all I can add. I'm using a Powrtuner.

I wouldnt be tuning a car without a wideband imo. Car sounds like its running to rich at idle.
