    torque fluctuating

    I need help with my camaro z28 (year 2000).

    The torque fluctuates when the car stands e.g. in front of a traffic light or in an drive in. then the automatic drive is in level "D" an i just hold my foot on the brake. after a few seconds it begins to fluctuate.
    sometimes the engine brakes down...

    it happens only with a warm motor...

    has anyone an idea? thx a lot!

    Have you checked your torque fluctuation valve?

    Kinda hard to diagnose without actually being there, but I would first look at it as a missfire problem, and would first look at the sparkplugs/wires. Be absolutey certain they are all snapped on together completely.

    No Check Engine light?

    Depends on what you mean by torque fluctuation, and where it happened, and who I was with when it happened....

    - no check engine light
    - pc diagnostic says: no problem found
    - ignition plugs were changed not long ago
    - exhaust gas recirculation valve was changed

    im glad the plugs where changed but that doesn't mean they are right..by torque fluctuation are you refering to your rpms bouncing..giving it a surging feeling? if soo...look into a vacuum leak or a stuck iac valve

    Aha. Was your car doing this before the spark plug change? Did you change the plugs to try to fix it?

    Well I hope they don't bend you over the counter. To me it sounds like a vacuum leak. let us know what they find.

    So, you changed the plugs then shortly after the problem started? I've seen more than 3 people here on this forum who have changed their plugs, sworn to everyone that they made sure the plug wires were all connected, then had to admit later it was a not-fully-connected plug wire after all. Or an almost closed plug gap on a new plug. Usually happens after a new plug installation, or something that required spark plug removal (like headers). If I were you, I would disconnect the plug wires, remove the spark plugs and double check the gaps, then reconnect the wires. I know the back right bank plug is a bitch, but at least if it is the problem you will fix it yourself instead of paying someone.

    Good Luck!

    Yea or burned a wire up because it fell out of a loom. Also make sure the plugs are tight. you may laugh but I can't tell you how many times people say they got the plugs tight and it turns out they were loose.

    Wrong plugs?

    All cables are okay and in right position.

    Could it be that the wrong plugs were installed?
    Does the Camaro need normal plugs or Titan plugs?
