dying issues

[comanche32]

I have a 90 4.0 and it has some running issues if it starts up revs high for a second and idles down it won't die. but sometmes it cranks a few times doesnt idle high then it will die this almost always when the engine is first started. but sometimes when it dies I can smell gas. it runs very smooth on the hiway just doesnt idle the greatest. ive cleaned the IAC it made no differance. driving me nuts

anyone have any ideas
