Car stumbles and dies..
So I have no idea what si wrong with the car, on hot days after driving for over half an hour or so the Tachomaeter will "flicker" and it feels like no gas is getting to the engine needless to say it dies and will start back up but will have the same issue again.. I have a 1990 305 TBI with all the following new: Fuel pump, Fuel Filter, Fuel injector filters, Distrubitor, Cap, Rotor, Wires, Plugs, Ignition Coil, MAP sensor, TPS, Vaccuum lines ( year old), I did the code reading and got codes 21,23,42 and 45, The only time the service engine light soon has popped on was during this issue, Any help would be greatly appreciated.

Well replaced the gas cap and purge valve, Just got the new EVAP canister filter today gonna go ahead and install it, I notice after driving I will unscrew the gas cap and can hear the gas tank expanding like it was building up too much pressure maybe breather is clogged? Not sure yet so gonna try to unplug it.

Just remeber after you install the new purge valve and the cannister to adjust the TPS. other wise it wont run right.

Thanks for the tip, I decided to get a new gas cap while I was at it since the old one didnt want to screw on correctly anymore made a huge difference now just figuring out idling issues but hey thanks for all the help!
