po302 OBDII code

After pulling P0302 code off my windstar, I replaced the wires and plugs thinking this would do the trick to get the engine light off. Also pulled a P0401-Egr code. Now 401 is not coming up, just the 302. Any ideas on what could be the problem? I am still replacing the egr valve this weekend, I've already replaced the egr sensor. What's the next logical step?

Sounds like you'd benifit from the lower intake cleaning (which cleans the EGR ports). Try a search on this topic. Do not swap any EGR parts until you do the cleaning.

302 is a misfire of #2 Cylinder - I just went through this & found a bad coil pack (Fairly common problem) - Try checking the spark on the #2 wire with a timing light & see if the flash is constant - Also could be a stuck fuel injector or an internal cylinder/valve problem - Good Luck
