i having a problem with my 98 continental. it started with a misfire, i tried to cure it with new plugs ( motorcraft- gapped correctly) no help. checked all the boots on the coils. there only 2 years old. coils seem to be fine. wiring seems to be fine. so i figured maybe an intake leak, i take everything apart to replace all the gaskets (upper/lower/throttle body/egr) since it was about that time anyway (154K) i get it back together and it runs like hell, turns out the harbor-freight torque wrench i was using was wayyyyy off.so i loosen everything back up and do it again with a in-spec torque wrench. and it runs flawlessly....until it warms up. then back to misfiring and now the new symptom of idling high. i took it apart again to see if anything went wrong when i was re assembling and everything was fine. clean and ready for a good seal. so i get back together with no change in problems. its leaking right where the lower intake manifold runner control is, on both sides. i found this using some throttle body cleaner sprayed on while it was running. theres no reason why it shouldnt be sealed correctly, its at the correct torque spec and brand new gaskets with clean surfaces. its a 1998 and apparently had a plastic lower intake manifold, with the intake runner control. i looked at a 01 continental motor and it didnt have any lower intake manifold and didnt appear to have any intake runner control. im wondering if i can just use an 01 intake an bypass all the plastic lower intake crap. suggestions?
