Saw on the news here in philly about the different code readers u can buy to ck codes yourself. trouble is they dont go below 96 and i have a 91. anyway I can ck codes myself BEFORE taking to mechanic and paying the HIGH fee of diagnostics?
My car is acting up and service eng soon lite comes on about 1-2x a month . goes on for a bit then goes out. had mechanic ck this last yr and he said nothing came up. so could it be a faulty something that is causing it to go on ? i dont think so.
when i drive its ok, when i come to stop and idle it feels like it shudders and may stall, but doesnt. then RPM gauge sits at line before 1 but the needle bounces and u can feel engine , its rough. if i put car in neutral its better or park. but as soon as i go back into drive it will shudder and feel like its going to stall.
my car has 128K on it. Id like to know how i can ck and change plugs and wires myself. i keep reading about O2 sensors and eng vacum cks for leaks. i guess i need a mechanic to do that for me. ck idle speed and mixture too.
any ideas on doing this myself and cking codes myself, even without those code readers?
thanks
