You said you LTFT'* are 16.4, is that +16.4? or -16.4?
Because +16.4 is super lean and that will surly cause KR.

i never noticed if it was either...
if thats super lean, I would think it would pull more like 15-20 degrees of KR, my 93 sure did

the PCM can adjust the injector timing better to combat lean conditions. let us know if it was 16.4 or -16.4. I am going to assume you didn't see a dash so it was lean. If this is the case, Clean the maf sensor and turn up the psi on the AFPR. rescan

Hang in a sec. The LTFT'* you see are the PCM showing you that it sees lean and adjusting the fuel trim aka amounts up to compensate. In the higher rpm'* you will see KR from it.

Matt... this is the current issue I am trying to combat.

How cold is it there?

Some of the LTFT could be form the weather. I see +7 to 9 in winter and -7 to 9 in summer. When it is ~70F I see near 0.

High positive LTFT (lean) means that the PCM is adding fuel based on the information from various sensors. This can be due to a bad MAF (mentioned above) or more likely unmetered air coming in somewhere (vac line break, hole, disconnected). Low volume or pressure from the fuel pump can also cause a lean condition (pressure may be there but volume may not, maybe a restriction in the fuel lines). An injector not firing all the way (clogged) could cause the PCM to ask for more fuel as well.

Finally an aging or old front 02 sensor may need to be replaced.

actually, the 02 sensor was the only thing I didnt replace...dont ask why...
Ill have to order a new one just as a good maintence item.

If you have a way to scan the car you can check the 02 readings in milivolts to see if the 02 sensor is oscillating high low rapidly. If its not moving, or its very slow you should replace it.

The scan gage can do that can it not?
If it can, then i will scan that parameter, for sure.

Yes
