Well the fuel used to cut out badly on the car once it got heated up and the opti was replaced and that is not it. Also i just had my h/c put in so the problem actually got worse where it is fine at idle but wont run. I have some friends working on it that are really good but its starting to make me wonder just what the problem is. The car is running extremely lean and not getting enough vacuum. I have new plugs and wires..and its not O2's because the SES isnt on.They have been messing with the tune, wiring harness and EGR but still no success yet. They seem to not think its the fuel pump because of the severity of what the car is doing. Fuel filter was just changed to. I am thinking it is just a bad wire or three that are corrupting everything. Any input? Thanks.
