Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956
Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)
Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.
These are the rules. Read them. Live by them.
1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.
2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.
3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.
4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.
The rules can and will be added to. Any updates will be marked in the title.
The rules for the overall forum can be found here:
http://www.cb7tuner.com/vbb/forumdisplay.php?f=144
Read them. You will be expected to follow them.

And clean the EGR ports.
Also, you mentioned changing the injectors. Did you replace all the o-rings with new ones?
They are old now and will leak fuel.

Have you checked:
Compression
For fuel leaks along the supply and return lines all the way from the tank?
Fuel pressure regulator
If automatic, check fluid level
Checked for brakes dragging
Tire pressure
Engine coolant and inlet air temperature sensors (if it thinks it cold, it will run rich).90 LX 4dr 5 spd 396,014 (sold 1/1/2022) - MRT: http://www.cb7tuner.com/vbb/showthread.php?t=201450

Low on the driver side end of the intake plenum is a sensor for the intake air temperature (nothing to do with the A/C). Resistance (without my manual) should be around 2000 - 3000 at room temperature and considerable lower when hot. Same for the ECT (engine coolant temperature sensor) on the right end of the head.90 LX 4dr 5 spd 396,014 (sold 1/1/2022) - MRT: http://www.cb7tuner.com/vbb/showthread.php?t=201450
