Default Update

So I removed exhaust after checking back pressure to make sure even though test confirmed the cat wasn't clogged. I've checked and double checked even triple check all wires and connectors between the battery a
and firewall. I have no obvious vac leaks. But I can say that you can feel the miss with greater regularity. I don't know how that can make a car stall at speed and then only when I make a right turn. I know I have to have missed something somewhere. Oh and FYI it doesnt stall even after driving and and having it stall. If I'm at a complete stop. And i'm not sure but I don't think it stall in reverse. At least it hasn't so far. Could it have something to do with the powersteering or rack and pinion. Or something of that nature. I'm running outta ideas.

Default Fuel pump

So I jacked the rear end of my car up completely off the ground and started the car. With the front still on the ground it idle long enough for me to get back to the trunk and it died and wouldn't start so now I'm thinking fuel pump or filter. Still doesn't explain dying when I turn right but I don't know.

Default Ok

SO I pulled the entire wiring harness and found a couple places were bad fixed them. It drove ok for I don't know like 50 miles or so before it started up again. Only now if I remove my foot from the accelerator sometimes it won't die.other than that it still has a miss in cylinder 6 and an o2 sensor fault code. I don't know what else to do. I hate to say it I think it has about whipped me. I can't stand not being able to fix something.

I haven't tested the fuel pressure yet. But I checked the avg fuel economy and it is saying it is 14.3 which is way lower than the last time I checked it. Also the vacuum line between the upper intake and the maf sensor had oil in it and it was all the way down by the maf sensor the sensor was still clean. I'm gonna take the upper intake lose I believe there was a tube in there that might have came lose. I'm going to get that gauge to test my fuel pressure in the morning. So I'll let you know something.
