Hey yall I was just curious if the trouble codes work like a domino effect. My situation goes like this my check engine light came on Mon. night no problem. Thurs. morning I go to work and she starts reving up and down from like 800 to 200 to 1000 rpm's to 200 or 100 at traffic lights and stop signs. Drove to work left her there and drove it from work to home Sat. morning and the same thing again but she cuts off once. I check my codes this morning and get 11(Camshaft pos. sen.), 21(Ignition signal circuit fault), 33(Oxygen sensor) I was wondering if anyone else had a problem like this and would a faulty camshaft position sensor cause everything else to malfunction. I dread going to the dealer on Monday. oh yeah i have a 94 GXE. If yall have any tips I thank you.

 

Why would you go to the dealer?
Your local mechanic should be able to handle it.
Mine can! (oh yeah, he has too he's my uncle )
