i have a 1997 ford f 150...184,517miles on a triton 4.6 v-8...i had to replace the intake manifold gasket last week due to a leak and missfire from the leak...after i got the truck back it would run and idle fine in park or driving down the road but when i stop the rpms would go below 500 and sometimes shut off. the engine light came on and i ran the code which stated insufficient egr flow...i then changed the egr valve but it did no good..the light came back on stating insufficient egr flow...and the engine still stalls at idle while in drive.i have since changed the tps and the egr control sensor but nothing has helped...i have also checked all vacuums for leaks and cant find any leaks.the engine light occasionally flashes then goes back solid...HELP!!!! please
