I have a stalling issue. When I come to a stop sign and rev the car up to about 1000 RPM it goes part way through and intersection then runs rough and stalls.

It starts back up right away. It seems to do this when it is very hot and maybe when I have less than a half tank of gas. It seems to run rough in the morning when started up but never stalls. It sounds like it is missing. It used to run very smooth only 30000 miles ago when I first got it, super smooth.

I replaced the plugs and the wires and the cap and the belts. This did not seem to help at all. It still seems to start rough in the morning.

If anyone has a good idea what this might be or suffered the same issue let me know. I really appreciate any idea or help.
Thanks so much!
