I’m gonna order up new ones and make sure they’re right, i painted over the old ones so i can’t use them to test. Thank you guys! I’ll let you know what happens as soon as we install them in a couple days. New O2 sensor is in, and gonna try a new TPS as well since it’s old, might as well make sure that doesn’t fail.

I am dealing with a rebuilt 2.9 B2 as well. with a rich condition. I am wondering if the new injectors I put in are the problem as well!
What injectors did you end up using with success?

thx- Andrew

I went with the Napa recommended injectors. Part No. CRB 2-18066 ans she fired right up and ran perfectly, was a little off on timing but ran perfectly.

Great news!
The new set of injectors and a timing twist has got her running well!
I got to take my first drive in her after a long engine rebuild. Very Happy at how she handles!

Glad to hear it! Now for the fun break in process lol! That’s a good looking ‘90. Glad i could help you out in your diagnosis, seems like a few of the parts for these get a little mixed up, just gotta be careful what you find, i’ve found having an OE part number really goes a long way!
