I've got a 1994 h22a prelude. it has this problem starting when the motor has warmed up to operating temperature. It starts fine when its cold. if i turn it off 5 minutes or more after its reached operating temperature, it doesnt start straightaway. i have to wait 5 to 10 minutes for it to cool down a little, and then it will start. if i try to start it too soon after turning it off, it fires and for a second you think its running and then it dies. anyone know how i can fix this problem? thanks.
