main issue of rough idle
Dear All,
on my 1997 Blazer I have a idle instability of around 80 rpm when I run in Drive. I have no failure code stored and putting money in it. new air filter replaced the spark plugs replace two O2 sensors cleaned the throttle body and bypass valve. Any ID out of experience what could be the driver for this. On the tec 2 all values looks to be in range. I apresciate any good hint. Thank you poeple. bob |

Re: main issue of rough idle
when the cap's contacts and the rotor wears out you get misfires. cap and rotor is a part of every tune up |
