Engine Performance problem
1993 Buick Roadmaster V8 All Wheel Drive Automatic 127000 miles
i drove my car for 25 mins on the highway, let of the gas and pressed on the break for 2 seconds at a stop sign an pressed on the gas again and my car just died. And now it will starts but runs rough, does not wanna go over 2000 rpms. When u let it try to idle it dies. It wont stay running long enough to put it in gear. I have checked the fuel pump, (listening for it and took off the fuel line from the back of the pressure regulator) and the gas comes out fine. Changed the fuel filter. Put the gas in a glass and checked to see if anything was in there. Dirt or water. Checked all the lines. Checked the distributor cap all the wires and plugs. Changed the fuel press. Regulator. The injectors r working fine. I checked those wires too. When u spray carb cleaner in it it runs fine.I have been fixing an driving a roadmaster for 9 years and im lost. For a video of wat is happening go to qik. Com an type in roadmaster92 and its the second video. The clicking noise you will hear in the video is coming from under the car. Could it be a cloged catalytic converter?
