So I have had this FI set up for 7 or so years. It is a TPI set up out of a 92 camaro. My jeep barely ever gets driven due to the normal one thing after another problems. Anyways I have I've been putting a lot of time in it lately to get everything running the way it should. It was a gas hog (6-7mpg). In September I found major vacuum leaks and mis routed vacuum lines. I fixed all of that and I noticed it was not running nearly as rich as it was before- good thing. Then the tranny died 2 days later-bad thing.
I have always thrown an engine code since the swap (24-VSS and 43-knock sensor). I have replaced the sensor twice. It doesn't clear The code. I just finished a trans swap that I now have an electric VSS. I noticed that when it was cold it would run real crappy for a couple of minutes. So I decided to pull codes tonight and got 24 and 43. So I decided to wire up the VSS to the computer to at least get rid of one code. Now it runs super rich and when the tires move the engine basically dies. I can sit there and rev it all I want not moving, but the minute I move the engine dies. I am now assuming my computer allowed me to drive before without because it never knew the wheels were turning. I have read it could, be bad knock, bad wire to knock, or the ESM. I also gather that because of this my computer could be taking out as much as 20 degrees of timing. Hence it dying. I have a feeling it's my computer that is bad. Before I write my life story, I'm just wondering if anyone else with TPI swaps has had similar problems. Thanks
