Howdy all, I'm new here so please go easy on me. I have an 89 F-250 w/460 and 5 spd. I am getting the check engine light all the time. Pulled my codes and got 327. Egr postion sensor. Book says this year truck should only have 2 digit codes. I'm positive I read the codes right so what's up with that? I also had the egr position sensor and egr valve replaced in april. I've only put about 5 k miles on it since then. The other problem is my clutch pedal gets hard sometimes. Where should I look for that??? I have 150k miles on this rig. It has to last another year. Thanks. John
