check engine light came on? (#43 O2 sensor)

Re:check engine light came on???
ok I got #3 manifold absolute pressure (map sensor) and #43 Fuel supply system. Is this ok to drive on the highway to the dyno 1.5 hrs, or should I find a trailer? I know how to reset the ecu, but what should I do about my codes. do you think the tuning will take car of that problem?

read this thread. You might find what TurboEF9 (Jason) says to be interesting considering your code 3 (MAP).

Re:check engine light came on? (got the codes now)
ok, I reset my ECU, and called an import dyno and they told me that the MAP sensor code was probably caused by having my settings too lean on the highway(that's when it came on)so my car was reading too much vacum pressure. They mentioned something about a missing link, but I didn't think that I needed that. As for the fuel code, I think that was caused by too lean and I boosted to 8 psi and then it started running like crap and almost died on me. I read the thread about the map sensor, but didn't help much.

Re:check engine light came on? (new code)
ok, went out on the highway after I made it even richer and code #43 fuel supply system came on. Any Ideas, probably just needs tuned. So....should I trailer it or drive it to the dyno?

Re:check engine light came on? (code #43 fuel system code!!!)
i'm getting it done tomrrow ....but!!! Is it safe to drive on the highway at like 55-60mph when the fuel system check engine light is coming on? If comes on every time I get on the highway for about 2 mins then it comes on...why? I'm running WAYYYY rich, like -33 and sometimes -30% when I'm cruising. I just found out it's my O2 sensor, but it's a brand new O2 sensor...any ideas...
