horrible day for my gta.I went to advance auto and brought some high mileage Freon for the ac unit in my car i put a half of can of the Freon through the ac low side.to get the compressor to engage because it was locked.it as in the ac compressor started to engage off and on but it wasn't consistant so i shut the car off to go inside of advance auto to buy one more can of Freon.When i attempted to start the car it would turn on and idle for like 2 to 4 seconds then it would turn off on its on.Like it had just died or something now as long as i slightly press the gas the car will idle normal.when i take my foot off the gas it dies


these are the things that i inspected.

the injector fuses
vacuum lines
spark plugs wires
throttle body
throttle cable
checked va lines to sd sensor


here are some of the things that i corrected

installed a new coil
sprayed throttle body cleaner in the throttle body
reseat all spark plug wires
advanced the distributor a tiny tiny bit to increase idle pass 500 rpm

with all that i have done it still dies and i dont know why any ideas
