So in desperation to get the car running before I get the starter I get my brother to help me push the car down the block to jump start it. As we're doing this a small child sticks his head out his window and says, "Mommy their pushing Hotwheels cars." Which I thought was humorous.

I got the starter in the car last night and it started right up. Although my new starter seems to be a hair longer and my rear mounding bracket doesn't line up. I just have to widen one bolt hole about a half an inch and it should be good. It idles very nice, so I guess I didn't screw up the distributor placement. But the when in gear and moving the car accelerates very slowly (bogging) through 1-2800rpm and then takes off at around 3000rpm. Which is what it was doing when my fuel pump had a hole in the (in tank) gas line.

Also 3 minutes into driving I get a "Check Engine Light". I'll try and pull the code tomorrow and check the fuel pressure from the line to see if my fuel pressure is low. And I'll check the fuel filter.

This just seems to be never ending.. What symptoms would I be having if my catalytic converter was plugged?
I wanna go fast.

Finally got a chance to do some work on the Fiero today. I pulled the code and got a 12 and a 13.

To my understanding 12 is the general, it's all good code, and 13 is oxygen sensor error or could bethrottle position sensor sticking or bad wiring connection.

I'm not exactly sure what wiring this is however.

Also is says in my book that: "The oxygen sensor, if open, should set a Code 13."

Does this mean it's probably the oxygen sensor rather than the throttle position sensor. Also is the exhaust sensor not supposed to be open? Is there a way to fix this? Or do I just buy a new one.

This is one I don't have an exact answer for, hopefully the good doctor can offer some advice, however from a V6 standpoint, there is an O2 sensor ground on the drivers side, firewall head that must be attached or it will set an O2 error.  I would look for the engine to harness grounds and check for any that are broken or corroded.

You've entered a world...  where working blind with no scan tool is a 'no fun' zone.

Where are you located?  I might be able to find the time Saturday to scan your car if you can drive it far enough to get here (north delta).  I really don't make house calls anymore.
