Did I fry my ECU?
Last night I was leaving my sisters, at about 4000 rpm the car stuttered and jerked and died out on me.
Got back to my sisters, and it would run, but I was getting all sorts of weird readings from the air/fuel junk gauge.
Started playing with wires up near the o2 sensor, and as I moved them, the car stalled out. The o2 sensor wires were pretty tore up, from about 8 swaps, so I figured I'd replace it.
So i did this morning, and I am still having the same problem. Biggest thing you notice is the tach bounces all over...at about 3000rpm it jumps to 5000rpm on the tach and the CEL comes on and the car stalls out. Now its completely dead. If I turn the key to the on position, the CEL comes on very dim, and there is a constant ticking noise coming from under the dash, like around the fuse box. Possible bad relay? Let me know what you think.
