22re running rich need some help!
Have done a few searches on here and have come up with a few things to ask you guys! I have adjusted the TPS according to 4crawler. Now Im moving on to other things that could cause this. When i fisrt start the pickup in the morning it blows some black smoke and kinda runs ruff. After driving for a little bit and I come to a stop at a light or what ever I can smell that its running rich. So I have checked the coolent temp switch and have the right ohms but have read that that still could be the problem. Also I want to check out the cold start injector to see if it running all the time. How do i test the cold start injector? Any other test that I can do on the coolent temp switch? Another thing that I did do was go to the dealer and get the right T-stat. Any more ideas are welcome just want to get this thing fixed!

Mine also runs rich. in the past 2 years I've replaced cat, o2, egr modulator, tps, afm, and plugs cap rotor and wires, adj valves. all to get it to pass emissions. which it barely does. still runs rich and sloooow.
My exhaust is pretty shot and that may be part of the problem.
It used to pass even without a cat.
