What if your second o2 sensor (the one by the cat) was open to the open air? would it make the car run rich? what are the signs of a bad o2 sensor? what are the signs of a bad ect? |

1) It would throw on the CEL 2) No 3) CEL Light 4) ect? Do you mean ECU?This is probably no help to you. In order to answer your questions a little better, give us a little more info as to what your thinking and what your Metro is doing. If you Metro is running, I'm 99.999% sure you can rule out the ECU. They VERY rarely go bad.

ECT Senosr. Got it. You have a '98 thats good. With OBDII it is very easy to check on the senors to make sure they are ok. . $20 and your phone and your in the game! ![]() Link--->OBDII ELM327 Bluetooth Connector I would check fuel pressure again: Link--->TESTING INSTRUCTIONS AND SPECS FOR TESTING FOR A DEFECTIVE FUEL PUMP- Check for pressure leak down after you turn the car off. Could be a sign of leaking o-rings around the injector or a leaky injector itself. Could be a clogged/dirty injector. blue rhino offers a cleaning service. Contact him for details. |

It's not just for codes, it also displays live data so you can see what the sensors see. I'm still betting on:

Injector was my first bet. So i put in a new one' no change. Later i put on a different throttle ody, .so the car has had three injectors in it. |
