94 tercel die when hot

[quote:7bc3389a92="alancylu"]hi,
my 94 tercel, 210K, working fine when it's cold,
when it's hot, when you press gas a little, it's idle rough and die, especially when the heat fan is spinning if you press gas a little it will idle rough and die, when i try to restart it, it will blow black smoke but won't start. After i let it cool down about 30 mins to one hour, it can start again.

Please help me, i am really scare to stop in front of traffic light, because it could die any second if i press gas

Any response will great appreciate.[/quote:7bc3389a92]

Find the PCV and EGR valves remove it and clean it up good-make sure both has vacuum and works. BTW also the IACV-then comeback with your findings

Before I put this Tercel on the operating table for Biopsy to get to the problem
