Question about 1998 Pontiac Bonneville
The car will start fine and run, as long as I leave my foot on the gas pedal. I remove pressure and the car will stall out.
The car has a new battery, plug, cables, and filters. I had the alternator and battery cables tested about six months ago and they were fine.
What can I do to fix this, its been a problem for about 4 months.

Sounds like your fuel pump is going bad! The more you press on the pedal the more demand is on the pump and it cant keep up cuz its junk. Try to limp it to a shop to replace it, unless u wanna do that yourself.....

sounds like your IAC (idle air control valve) located on the throttle body towards the front of the engine held in by 2 torx screws. the iac controls the idle if the car when your not on the gas. i will post the steps to clean the iac and the passages that the iac goes into.
1. disconnect the iac connector
2. remove the iac
3 clean the iac pintle valve and check for wear
4. clean the passages that the pintle valve sits in (usually carbon build-up in there, you may need to remove the air intake tube and air filter box to get to the passages in the throttlebody)
5. if the iac looks ok and the passages are cleaned re-install and put everything back
6. start car and see if it idles like normal when warmed up. you may need to give it a few tries for the iac to re-learn its proper position so give it a few warmup cycles
7. if it still stalls check for proper operation of the iac via ohming out the connectors (if you look it up on google you will find the specs at which the iac is supposed to operate)
8. if the iac is working properly, check for vacuum leaks on the intake manifold and vacuum lines.
9. if no vacuum leaks are present and the iac id working properly after cleaning have a shop check the ecm (engine control module) for a bad circuit board, i've seen that haoppen as well
hope this helps!

djn, I believe you have some accessory that is on when the key is in the off position.
Check to make certain glove box light is not on when the glove box door is closed and the trunk light is not on.
If you have an aftermarket radio or any added accessories make sure they are not wired direct to battery voltage.
If all that checks out, disconnect the battery negative and connect a test light between the battery and battery cable. If the light is on you have a drain in the electrical system. Leave the light connected and begin removing 1 fuse at a time until the light goes out, that will tell you what component or circuit is draining the battery.
Last resort, you may have an alternator drawing the battery down.
Good luck and let me know.
