Car problems!
i have checked all my connectors and they are sll still hooked up. I replaced all 8 spark plugs becaue they were all looking like this.

The wideband a/f is showing rich as hell (10 range) just as the spark plugs confirm.
Anyone have anyideas...i have been working on troubleshooting this for a couple weeks no with no progress....
i have access to a scanner and can get any numbers if anyone needs that to help figure out what is going on.
Also my alt is acting up and the factory gauge is showing some major voltage issues but my multimeter shows 14v...but this all happened when the car started acting up, so could it be part of the prob?
Excessive fuel pressure
Bad O2s
Partially blocked intake
Really bad tune
still thinking o2's kinda...replaced 1 and still bad
intake is good, i have taken it off and checked the whole track (STS car)
i cant think of any reason why the tune should have changed
