My 92 Camaro 5.0 TBI was running fine one day and then it stalled out like it wasnt getting gas. To make it short....I replaced the throttle position sensor, idle air control valve, fuel filter, air cleaner gasket and checked and actually replaced the vacuum hoses. The PCV is fairly new and in good shape. I dont have the equipment to check fuel pressure but I disconnected a fuel line and it had a good amount of pressure in it. It shot out about 3 feet. While looking in the throttle body...I can see that the injectors are spraying. Before I started replacing parts, the car would bounce up and down between 1800 rpm and 100 rpm (almost stalling before shooting back up). When I put it in gear it would stall out quickly. I thought I had it fixed even though it idles high but when I put it in gear now....it does the bouncing rpm thing again and stalls out if I dont hit the gas at the right time. It idles at 1100 rpm when I start the car and when I put it in gear...like I said it bounces and wants to stall. Also all the plugs and wires appear to be in good shape. Any ideas what this could be? We're pulling our hair out here trying to fix this. Thanks for any help.
