Help with datalog (Scan9495 file attached)
 

Hi all, hoping someone experienced can help me find any anomalies in my datalog:

https://drive.google.com/file/d/1xYy...usp=drive_link

Symptoms:

• runs rich (as seen in the BLMs)
• rough idle

- from time to time there's a shudder in the engine (whole car shakes) after it gets into 3rd or 4th gear (this happened from 850s-900s in log)

Background:

• new opti, waterpump, and seals
• new air filter
• new fuel pump (fuel pressure is 42psi at prime and 36psi at idle)
• new evap system
• new egr valve (rest of egr components tested fine)
• injectors test at 12ohm cold and 12.9ohm hot (they don't leak down when fuel is primed)
• fuel pressure regulator doesn't leak, psi changes when engine is idling and vac line is removed.

My BLM seem to be split at times. The O2 sensors vary from each other as well. But I don't know enough to determine what's normal and what isn't.

Any help is welcome guys.
Thanks.

Thanks for the response, and for all the posts over the years. For the post you linked, are you referring to this part "AT THIS POINT (06/03/24) I AM NO LONGER REVIEWING DATA LOGS.". If so, are there not others on the site that can help? I assumed there would be.

There's nobody left here. 100,000+ members, and no more than a 1/2-dozen who check in maybe once a month or so, with the intent to help - all but one are LT1 owners (present or past). Not aware of anyone among them that reviews data logs. I noticed a couple things in the visible attachment on Firebird Nation, I'll respond there.

Most of the time I spend here is chasing off spammers. Ditto on Firebird Nation. There are three “administrators” on FN, used to be five. It's a much more active site, but I seem to be the only one fending off the continuous attacks of spammers. I'm trying to get the site owners to add an “approval” step for new members, but so far being ignored.

Hence, putting in way too much time on the three sites I handle (as I see you discovered). No time left for scan logs.

Oh wow, that's sad to hear. Feels like I've joined the party after everyone's gone home lol. I appreciate your help on the FN forum Fred. I've added my response to your questions there.
