I took Chris's advice, and picked up NTK's 22013, listed for most 5.0's I crossed. Was surprised that they were the cheeper option for the most part. NOT the way my luck runs on most part costs
HOWEVER.... When I pulled em, the driverside looked good, but the passenger side was literally SOAKED in raw fuel
When I pulled the plugs I found the same, drivers were rich, but not bad for a highly modified car without a tune, the pass were again dripping wet. When I ran thru the plug wires after getting it running (no better I might add) to be sure they were seated I also noticed the pass side was MUCH cooler, I could barely touch the driver side boots, or keep my hands in the area. Pass side, I could touch the boots almost comfortably, and keep hands in the area a lot longer.
This was a sudden "catastrophic" failure, I drove to work fine, 12hrs later I could barely get it home. Dam thing was backfiring in the header tubes (popping under hood) surging, missing, and smoking like a diesel "rollin' coal" ( I could actually see the clouds in my mirrors in the headlights of the cars behind me)
. This is not coolant or oil smoke, it is fuel. I also realized that the check engine light does not come on when cycling the key to start. I figured this out when I didn't understand it throwing me no codes whit such a sudden change. Gonna see if I can pull codes next.
Although this is not a SC, I am hoping some of the EEC IV guru's out there will chime in. I am not sure what could cause a BANK to BANK fuel/spark problem to dump raw fuel like this, other than the pass O2 reading way lean. That is why I figured the O2 would correct it. And I DO believe it is a FUEL problem, I burned through 1/2 a tank in 50 miles and a couple 1/2 to 1 hour trouble shooting sessions in the drive
. If it won't "talk" to me would these symptoms (no communication, right bank only fuel/spark issue, no check engine lite) indicate a computer failure? In all my years with 5.0 and SC's I have NEVER seen the computer fail, but.... always a first time
Any thoughts appreciated
