somthing acting up

okay so i was driving one day and my car starts to sputter.. and i look under the hood and try to figure it out..didnt, i got home pulled it into the garage.. and i smelt somethign rank. so
1. my cat is clogged (maybe thats it)- i orderd a test pipe.
2. i replaced all my plugs and wires and it fixed it...for a while
3. i noticed the distributor cap was corroded(i replaced it) fixed it for a while.. and now its doing it again.
4. i pulled each plug one at a time. and obviously it bogs down when i pull them.. except for the 3rd plug..so id guess maybe the 3rd plug is bad.

AND
for some reason my dash lights dont work, if i turn on my head lights.
and something sparked in the back of my guage cluster like 3 weeks ago, and since then the lights dont work. and i cant switch my blend door. (stays only at defrost and feet, cant go to anything else)

You could have a lose wire grounding somewhere and baking.

hmm...well i dont know i havent gone into tooo much detail in checking it, so i just havent been driving it all too much.

but thanks for your help.

evey fixed the problem?

we tried fixing the cluster lighting today, but I guessed wrong as to what was causing the problem.

did you try the distributor itself? rotor?

no..but i know its not the distributor.still been messin with it..i think its the MAF..becasue the car is fun unless its super duper cold

I had the same problem I just fixed it today. Cylinder 2 was not firing.

I changed

Distributor
Cap
Rotor
Plugs
Spark plug

Timed it all over and bam sparking on all cylinders, still cuts of at high rpm. It might be the Maf Ill probaly changed that tomorrow.

hmm...i dont know how to do timing...but.. my car hasnt been acting up...but if does..ill def just have to change all of that

hey thanks a lot man
