I recently had my check engine light come on and it called out the MAF, I replaced the Maf and it took care of the problem. I may have had a additional problem as I noticed before that the car would chug when stepping on the gas. After replacing the Maf it popped a code for a mis-fire on # 2. I replaced the plugs and dont have the code any more but now it pops a code for excessive EGR gasses. The car still misses when stepping on the gas especially when going up a hill. I was going to change the plug wires as I believe that the last time (previous owner) didnt replace all the wires, but only one or two (wire colors dont match) Im kinda at a loss on what to try next, and would like some ideas before I totally give up and take my chance with the local mechanic. Could this problem be caused from a vacuum problem or a fuel problem. My thunderbird is a 4.6 v8, I bought it used from a co worker who took pretty good care of the car and i'm pretty sure he had the EGR valve replaced prior to me buying it. It has 114,000 miles on it. I love the car and have not had any problems up to this point. I read about a program that can be loaded on a lap top for the OBD-II that shows more in depth anaylis. Can you explain a little about this and any help with troubleshooting this problem.
