prelude stalling

ok im gonna try to make a long story short. crank gear chewed timing belt so we replaced timing belt,waterpump, balancing shaft belt and headgasket. timing is good. cars starts up good. idles good. but once it gets warm it runs like shitt. once the car warms up it boggs down until like 3k then runs good. but it dies when it idles back down. like if ur just sitting in neutral and rev it it just dies when the rpm go down past 1k, unless u press the gas.it also does it if u drive it. it runs fine after 3k but when u go to come to a stop sign it just dies. no computer codes. took off egr and it didnt help. any ideas cuz we dont and we need some bad.thanks

noe one knows anything?

I've had a similar problem in another car i've owned, same symptoms. Was a ignition module. If i could get it to start i was ok as long as the rpm didnt drop. Hope i can help.
