Just got down replacing center link and idler arm, gave it a quick garage alignment, wow it drives much better now. Did pull hard left and had tons of slack, tight now.

After that I took it out and warmed it up, then data logged it:

Here are some screen shots idling after drive:

Holy huge pictures!!

Both B1 & B2 are maxing out lean. That changes the diagnosis. A problem with the MAF reading, a large vacuum leak, or some other problem that would make the PCM think the engine is getting less air than it actually is...

 

I have not been able to find a vacum leak, sprayed arround with carb cleaner. Not sute where to look next.

What should my MAF and Intake temperature readings be at idle when warm?

What are baselines for B1 & B2?

 

MAF & IAT readings are highly dependent on our ambient & operating conditions. To give you #'s, the IAT typically is a few degrees above ambient. MAF at idle for my old '00 Bravada was 2280Hz (0.6 lb/min). I'm not sure what you mean by baselines on B1 & B2. If you are talking about the LTFT values, as I stated earlier, ideally they would be near zero. STFT bounces around depending on the conditions.

 

Driving home today on the interstae the SES light came on again. Was able to log the trip, better data this time. SES was for to rich again!?!?
