Having problems with your Cars & Trucks ?

89 buick 3.3 car runs at idle but cuts off when at half throttle or 1 mile down road

\015 Fuel pressure maintains 35 lb at idle and 45 when giving throttle. The injectors were professionally cleaned 10,000 miles ago. Coil pack and module was replaced while trying trouble shoot. The mass airflow sensor was cleaned and corrosion was removed tbs sensor is working. I removed on injector wire and car stops I wanted to check if car lost injector signal. Could the intake be leaking at a place that you can't hear or find? I have not tried ignition switch yet car seems to maintain power to all componants. Car will idle forever but acts like it is losing fuel but it is not. I don;t want to start hanging parts on to find the problem it cost money and time. any more ideas?\015 Posted / edited by AnonymousUser on : 23-05-2022
